The side chains are: an ethyl- at carbon 4, an ethyl- at carbon 8, and a butyl- at carbon 12. This created an imbalanced situation, where there were, Manufacturing Extension Partnership (MEP), Resources for Continuing Education and Training, Quick Guide for OWM Contacts System (PDF), How to Request Publications using OWM Contacts System (PDF), How to Request Training & Transcript Using the Contacts System (PDF), How to Reset Password Using the Contacts System (PDF), The National Conference on Weights and Measures (NCWM), Commonly Used Metric System Units, Symbols, and Prefixes. Naming Aldehydes. Common nomenclature uses the older names for some organic compounds instead of using the prefixes for the carbon skeleton above. To avoid long and tedious names in normal communication, the official IUPAC naming recommendations are not always followed in practice, except when it is necessary to give an unambiguous and absolute definition to a compound. Metric Prefixes for SI Units . An official website of the United States government. Prefix Progress. Robert E. Belford (University of Arkansas Little Rock; Department of Chemistry). With one fewer oxygen than the "-ate" ion, the acid will have the suffix "-ous." For example, chlorous acid is HClO 2. See individual functional group articles for more details. A word to the wise: deca- (symbol = da) is a little used unit prefix. In the SI, designations of multiples and subdivision of any unit may be arrived at by combining with the name of the unit the prefixes deka, hecto, and kilo meaning, respectively, 10, 100, and 1000, and deci, centi, and milli, meaning, respectively, one-tenth, one-hundredth, and one-thousandth. {\displaystyle {\ce {CH3CH2CH2CH2C#N}}} Some simple examples, named both ways, are shown in the figure above. Legal. (di- after #,#, tri- after #,#,#, etc.). 3 is less than 15, therefore the ketones are numbered 3 and 9. Hydron is a generic term for hydrogen cation; protons, deuterons and tritons are all hydrons. Symbols as prefixes exist for large and small values, and every prefix and symbol represents an order of magnitude. They are combined to create, 4,8-diethyl. Prefixes in molecular compounds are decided by the number of atoms of each element in the compound. 185 femtometers to millimeters The suffix is -ane if all of the carbon-carbon bonds are single bonds (formula CnH2n+2), -ene if at least one carbon-carbon bond is a double bond (formula CnH2n), and -yne if there is at least one carbon-carbon triple bond (formula CnH2n-2). Note the increments or decrements by thousand 10+3 or 10-3 are used aside from hecto (centi) and deca (deci). Chemistry Organic Chemistry Naming Alkanes, Alkenes, and Alkynes 1 Answer Meave60 Sep 13, 2017 Refer to the explanation. Some examples of molecular compounds are water (H2O) and carbon dioxide (CO2). If the diameter of the plunger is $1.3 \mathrm{~cm}$ and that of the needle is $0.20 \mathrm{~mm}$, what force on the plunger would be needed to push fluid into a vein where the gauge pressure is $75 \mathrm{~mm}\mathrm{~Hg}$ ? However, double and triple bonds only take suffix form (-en and -yn) and are used with other suffixes. The first step is to count the number of each element. understanding and skills required) Key vocabulary. The group secondary functional groups and side chains may not look the same as shown here, as the side chains and secondary functional groups are arranged alphabetically. 9 S 6 7 P. lo 235 embers possess the group, have similar chemical a compler A Name / prefix st IUPAC Naming Naming of Hydrocarbons + Suffix DATE // Displacement JOOKS Prefix Meth Eth Prop But -Pent Hex Hept 6c+ Non Dec PAGE Suffix Alkanes ane Alkenes ene Alkoymes 'yne' Horexs C4 M10 ex Botone CH CH CH CH cyclo botane.. Use prefixes appropriately to indicate the number of each kind of atom. Alternatively, the suffix "-carboxylic acid" can be used, combined with a multiplying prefix if necessary mellitic acid is benzenehexacarboxylic acid, for example. When the hydrocarbons are substituents, there are several common names you may encounter: Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. For Example, CH3CO-R is called Ethanoyl-R. An IUPAC name also includes the names of substituent groups (aside from hydrogen) that make up the molecular structure. Six prefixes were added. IUPAC NOMENCLATURE OF ORGANIC CHEMISTRY- YOUTUBE VIDEO LECTURE RULES. Greek prefixes are often used for naming compounds. Note that some of the prefixes may change slightly when they are applied to the names. If just one atom of the first element is in the formula, omit the prefix mono- for that element. Chapter 3 Section 3 6 Molecular Compounds Formulas. According to the current version of Nomenclature of Organic Chemistry - IUPAC Recommendations and Preferred Names 2013 (Blue Book), simple prefixes (simple substituent groups consisting of just one part that describes an atom, or group of atoms as a unit, for example methyl, cyclohexyl, and isopropyl) are arranged alphabetically disregarding any The order of remaining functional groups is only needed for substituted benzene and hence is not mentioned here. INTRODUCTION Thus, because compound prefixes are unacceptable, symbols for decimal multiples and submultiples of the unit of mass are formed by attaching SI prefix symbols to g (gram). For example, MeV means million electron volts, units of energy. . The IUPAC nomenclature of organic chemistry, for example, uses the numerical prefixes derived from Greek, except for the prefix for 9 (as mentioned) and the prefixes from 1 to 4 (meth-, eth-, prop-, and but-), which are not derived from words for numbers. Everytime you reload these should rearrange. Dont get frustrated with yourself if you dont understand it right away. The shorter of the two chains becomes the first part of the name with the -ane suffix changed to -oxy, and the longer alkane chain becomes the suffix of the name of the ether. Hexa- definition, a combining form meaning "six," used in the formation of compound words: hexapartite. chlorofluoromethane, not fluorochloromethane. Section 9.1 Naming Ions OBJECTIVES: -Define a polyatomic ion and write the names and formulas of the most common polyatomic ions. If the carbon in the carbonyl group cannot be included in the attached chain (for instance in the case of cyclic aldehydes), the prefix "formyl-" or the suffix "-carbaldehyde" is used: C6H11CHO is cyclohexanecarbaldehyde. N 2 Cyclic alkanes are simply prefixed with "cyclo-": for example, C4H8 is cyclobutane (not to be confused with butene) and C6H12 is cyclohexane (not to be confused with hexene). The same suffix may be used with more than one series: Because of the common inheritance of Greek and Latin roots across the Romance languages, the import of much of that derived vocabulary into non-Romance languages (such as into English via Norman French), and the borrowing of 19th and 20th century coinages into many languages, the same numerical prefixes occur in many languages. See its etymology for details.). The prefix form is "amino-". The root language of a numerical prefix need not be related to the root language of the word that it prefixes. What is the prefix of 9? In general, carboxylic acids are named with the suffix -oic acid (etymologically a back-formation from benzoic acid). Alkenes are named for their parent alkane chain with the suffix "-ene" and an infixed number indicating the position of the carbon with the lower number for each double bond in the chain: CH2=CHCH2CH3 is but-1-ene. Identification of the side-chains. Numbering of the various substituents and bonds with their locants. First, you need to determine what type of compound it is. Three for forming multiples: mega, giga, and tera. Acid anhydrides (R-CO-O-OC-R) have two acyl groups linked by an oxygen atom. Prefixes, symbols, orders, and names for large . If a prefix form is required, "oxo-" is used (as for ketones), with the position number indicating the end of a chain: CHOCH2COOH is 3-oxopropanoic acid. When compounds contain more than one functional group, the order of precedence determines which groups are named with prefix or suffix forms. \[ \begin{align} 1,330,000,000m& =1.33\times 10^{9}m =1.33 \; gigameters\nonumber \\13,300,000,000m& =13.3 \times 10^{9}m=13.3 \;gigameters\nonumber\\ 133,000,000,000m& =133\times 10^{9}m = \; 133 \; gigameters\end{align}\]. How to Name Chemical Compounds. "cyclohexyl-") or for benzene, "phenyl-". What are the disadvantages of shielding a thermometer?

It is important that you do this as you will not be able to follow the science later on in the course if you do not understand the meanings of the terms used. 'anti', 'auto' and 'super' Prefix. What are the two applications of bifilar suspension? Several common-use numerical prefixes denote vulgar fractions. There are no exceptions for words comprising technical numerical prefixes, though. Metric Prefixes. springhill suites knoxville at turkey creek; p0171 . 2. So a memory stick with 1,200,000 bytes would be written as 1.2 Mbyte, not as 1,200 kbytes. You also need to know them to figure out the formula from their names. Its name means a hundredth of the length of a metre. The above list shows the 10 most basic chemistry prefixes for naming compounds, which come from Greek. Solve any question of Some Basic Concepts of Chemistry with:-. CH Four prefixes were added. "Milli" refers to 10 -3, while "nano" refers to 10 -9. Some of the SI prefixes denote negative powers of 10, i.e. to include a prefix that indicates the number of hydroxyl groups present (-anediol, -anetriol, etc.). Amides that have additional substituents on the nitrogen are treated similarly to the case of amines: they are ordered alphabetically with the location prefix N: HCON(CH3)2 is N,N-dimethylmethanamide, CH3CON(CH3)2 is N,N-dimethylethanamide. The -oate changes to -ate. "I got it right" and can skip the ones you know. The suffixes -diol, -triol, -tetraol, etc., are used for multiple -OH groups: Ethylene glycol CH2OHCH2OH is ethane-1,2-diol. For example, the prefixdeka is used (American English spelling) but not deca (British English). So we would say 16Gigabytes and not 16,000 Mbytes of 16,000,000 kbytes. The purpose of organic chemistry nomenclature is to indicate how many carbon atoms are in a chain, how the atoms are bonded together, and the identity and location of any functional groups in the molecule. For example,(CH3)2CHCH2CH2Br is named 1-bromo-3-methylbutane. Everytime you reload these should rearrange. what type of danger zone is needed for this exercise. For example, NO2 would be called nitrogen dioxide, not mononitrogen dioxide. For example, a chain of six carbon atoms would be named using the prefix hex-. SI Prefix symbols are featured in the chart and used to represent smaller or larger units by factors that are powers of 10. Lock A challenge for you to think more deeply .

NIST SI Measurement System Chart (2021) is a colorful chart explaining the 7 base units of the SI, prefix symbols, and features the Measurement League: Guardians of the SI. Rachel Lynette. SI Prefix symbols are featured in the chart and used to represent smaller or larger units by factors that are powers of 10. Guidance is provided to aid general public use of the metric system. The IUPAC nomenclature also provides rules for naming ions. Accessibility StatementFor more information contact us atinfo@libretexts.orgor check out our status page at https://status.libretexts.org. The ENG key takes large or small numbers and expresses them as integer multiples of 103 or 10-3, effectively converting them to values that can be expressed with SI prefixes. Alcohols (R-OH) take the suffix "-ol" with an infix numerical bonding position: CH3CH2CH2OH is propan-1-ol. 1 mono; 2 di; 3 tri; 4 tetra; 5 penta; 6 hexa; 7 hepta; 8 octa; 9 ennea; The following table of 24 SI prefixes ranging from 1030 to 1030 are currently recognized for use. This is essentially the roman numeral system that has already been explained, but it applies to non-ionic compounds as well. { "Metric//Imperial_Conversion_Errors" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Metric_Prefixes_-_from_yotta_to_yocto" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Non-SI_Units" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Physical_Quantities : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Prefixes : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", SI_Units : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "SI_Units_-_A_Summary" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Unit_Conversions : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { Accuracy_of_Spectrophotometer_Readings : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Density_and_Percent_Compositions : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Dynamic_Light_Scattering : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Significant_Digits : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Temperature_Basics : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", The_Scientific_Method : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", Units_of_Measure : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Volumetric_Chemical_Analysis_(Shiundu)" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, [ "article:topic", "prefixes", "showtoc:no", "license:ccbyncsa", "licenseversion:40" ], https://chem.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fchem.libretexts.org%2FBookshelves%2FAnalytical_Chemistry%2FSupplemental_Modules_(Analytical_Chemistry)%2FQuantifying_Nature%2FUnits_of_Measure%2FPrefixes, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), Prefixes for Decimal Multiples and Submultiples, status page at https://status.libretexts.org. *Note: These suffixes, in which the carbon atom is counted as part of the preceding chain, are the most commonly used. The alkyl (R') group is named first. The parent hydrocarbon chain has 23 carbons. The names of the first four alkanes were derived from methanol, ether, propionic acid and butyric acid, respectively. In Scientific Notation there is on digit to the left of the decimal, in Engineering notation there are 1, 2 or 3 digits to the left of the decimal, and you then use one of the Si prefixes that is of the magnitude 103n. In order to correctly convert one metric unit to another, you will need to determine which of two prefixes represents a bigger amount and then determine the exponential "distance" between them. NIST SI Measurement System Chart (2021) is a colorful chart explaining the 7 base units of the SI, prefix symbols, and features the Measurement League: Guardians of the SI. If there are two side-chains with the same alpha carbon, the number will be written twice. ), e.g. Follow. The prefix "D" comes from the Latin word dexter. Where an acid has both a systematic and a common name (like CH3COOH, for example, which is known as both acetic acid and as ethanoic acid), its salts can be named from either parent name. For historical reasons, the name "kilogram" for the SI base unit of mass contains the name "kilo," the SI prefix for 103. As there are two, we write 3,9-dione. con/co, etc. The R-CO-O part is then named as a separate word based on the carboxylic acid name, with the ending changed from -oic acid to -oate. There is also an IUPAC nomenclature of inorganic chemistry. If there is more than one of the same type of substituent/double bond, a prefix is added showing how many there are (di 2 tri 3 tetra 4 then as for the number of carbons below with 'a' added). Note also that some names are given using other conventions. Prefixes, Suffixes, and Roots are essential for vocabulary growth, and these worksheets are perfect to have students practice prefix, suffix, and root problems.WHAT'S INCLUDED: PRINT:40 WorksheetsAnswer KeysDIGITAL:120 Google Slides"Worksheet Style" Google SlidesSelf . Initially, all prefixes were represented by lowercase symbols. The common prefixes are given in this Table. Two for forming multiples: ronna and quetta. A .gov website belongs to an official government organization in the United States. Activity\(\PageIndex{2}\): Prefix to Value. The groups are on carbon atoms 3 and 9. They are modifiers on the root word that tell us the unit of measure. There is one triple bond between carbon atoms 19 and 20. For example, CH3CH(OH)COOH (lactic acid) is named 2-hydroxypropanoic acid with no "1" stated. If the oxygen is not attached to the end of the main alkane chain, then the whole shorter alkyl-plus-ether group is treated as a side-chain and prefixed with its bonding position on the main chain. The entire field of organic chemistry is devoted to studying the way carbon bonds. Ph.D., Biomedical Sciences, University of Tennessee at Knoxville, B.A., Physics and Mathematics, Hastings College, -ic acid indicates a carboxylic acid, which has the O=C-OH functional group. When you have a polyatomic ion with one more oxygen than the "-ate" ion, then your acid will have the prefix "per-" and the suffix "-ic." For example, the chlorate ion is ClO 3-. Links to other areas of the chemistry syllabus. Prefixes are often used for decimal multiples and submultiples of units. Answer (1 of 2): According to IUPAC, naming in organic chemistry (hydrocarbons) must be done in accordance of following; for 1 carbon - use 'meth' (single bond-methane) for 2 carbons - use 'eth' (single bond-ethane; double bond-ethene; triple bond-ethyne) for 3 carbons - use 'prop' (single bo. For example, (CH 3) 2 CHCH 2 CH 2 Br is 1-bromo-3-methylbutane. A $3.2\mathrm{~N}$ force is applied to the plunger of a hypodermic needle. According to the IUPAC system of nomenclature -al is attached as a suffix to parent alkane for the naming of aldehydes. Section 7 1 Naming and Writing Formulas for Molecular Compounds The prefix in the name of a binary molecular compound tells how many atoms of each element are present in each molecule of the compound to Prefixes is shared under a CC BY-NC-SA 4.0 license and was authored, remixed, and/or curated by LibreTexts. PDF. By suffix, it is meant that the parent functional group should have a suffix, unlike halogen substituents. NOTE: If you already know an answer you can just click "I got it right" and move on to the next. If other functional groups are present, the chain is numbered such that the aldehyde carbon is in the "1" position, unless functional groups of higher precedence are present. You should contact him if you have any concerns. However, cis- and trans- are relative descriptors. Section 9.1 Naming Ions OBJECTIVES: -Identify the charges on monatomic ions by using the periodic table, and name the ions. Spelling. The secondary functional groups are: a hydroxy- at carbon 5, a chloro- at carbon 11, a methoxy- at carbon 15, and a bromo- at carbon 18. 3 Here is a sample molecule with the parent carbons numbered: For simplicity, here is an image of the same molecule, where the hydrogens in the parent chain are removed and the carbons are shown by their numbers: The final name is (6E,13E)-18-bromo-12-butyl-11-chloro-4,8-diethyl-5-hydroxy-15-methoxytricosa-6,13-dien-19-yne-3,9-dione. The common prefixes are given in this Table. Tetra- is a combining form used like a prefix meaning "four." It is used in a great many scientific and other technical terms. In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended[1][2] by the International Union of Pure and Applied Chemistry (IUPAC). Every hydrogen is joined to a carbon. The . "semi-" redirects here. How did you use the result to determine who walked fastest and slowest? Note also that some names are given using other conventions. For Latinate 21, 22, etc., the pattern for the teens is followed: In organic chemistry, most prefixes are Greek but the prefixes for 9 and 11 are Latin. Second element; named as if it were an anion (-ide suffix) always gets a prefix mono - 1 penta - 5 octa - 8 di - 2 hexa - 6 nona - 9 tri - 3 hepta - 7 deca - 10 tetra - 4 C. Naming Acids; Binary Acids (two elements - hydrogen + one other) a. prefix "Hydro" + root of second element + "ic" suffix . Helmenstine, Anne Marie, Ph.D. "Organic Chemistry Prefixes and Suffixes." It is IUPAC convention to describe all alkenes using absolute descriptors of Z- (same side) and E- (opposite) with the CahnIngoldPrelog priority rules. When numbering from right to left, the ketone groups are numbered 15 and 21. NOTE: If you already know an answer you can just click "I got it right" and move on to the next. Other articles where prefix is discussed: steroid: Steroid numbering system and nomenclature: trivial nomenclature, a number of prefixes are often attached, with locants, to the names of steroids to indicate specific modifications of the structure. The rest are named with a Greek numeric prefix, with the exceptions of nonane which has a Latin prefix, and undecane which has mixed-language prefixes. ThoughtCo. Simply add the name of the attached halide to the end of the acyl group. Numbers are used to identify the position of the substituent. * SI base or derived units with special names may be used. This material has bothoriginal contributions, and contentbuilt upon prior contributions of the LibreTexts Community and other resources,including but not limited to: This page titled 2.7: SI Prefixes is shared under a not declared license and was authored, remixed, and/or curated by Robert Belford. Carboxylic acids attached to a benzene ring are structural analogs of benzoic acid (Ph-COOH) and are named as one of its derivatives. Metric Prefixes for SI Units . Commas are put between numbers (2 5 5 becomes 2,5,5), Hyphens are put between a number and a letter (2 5 5 trimethylheptane becomes 2,5,5-trimethylheptane), Successive words are merged into one word (trimethyl heptane becomes trimethylheptane). A molecular compound consists of molecules whose formula represent the actual number of atoms bonded together in that molecule. These compounds are held together by covalent bonds between atoms in the molecule. Prefix Prefixes are added prior to the root of the compounds IUPAC nomenclature. For example, CHCl3 (chloroform) is trichloromethane. For example, CH3COCl is ethanoyl chloride. A prefix to the name comes before the molecule. 4. You need to memorize the red SI prefixes in table \(\PageIndex{1}\). For example, C6H6 is named benzene. Introduction to Chemistry Prefixes Number of Atoms: Prefixes 1: mono 2: di 3: tri 4: tetra 5: penta 6: hexa 7: hepta 8: octa 9: nona 10: deca The above list shows the 10 most basic chemistry prefixes for naming compounds, which come from Greek. Branched alkanes are named as a straight-chain alkane with attached alkyl groups. The prefix of the molecule's name is based on thenumber of carbon atoms. For example, a chain of six carbon atoms would be named using the prefix hex-. It should have the maximum number of substituents or branches cited as prefixes. novem-Prefix Prefix meaning Sample words; novem-9: novena: prayers said over nine days: deka- or deca-10: decade: a period of 10 years: cent- The carbon skeleton is how many carbons are linked to each other. The official language of the BIPM SI Brochure is French and includes an English translation but provides no pronunciation guidance. They are prefixed with a number indicating the carbon the group is attached to, counting from the end of the alkane chain. You are planning an exercise that will include the m16 and m203. The ordinal series are based on ordinal numbers such as the English first, second, third (for numbers higher than 2, the ordinal forms are also used for fractions; only the fraction .mw-parser-output .frac{white-space:nowrap}.mw-parser-output .frac .num,.mw-parser-output .frac .den{font-size:80%;line-height:0;vertical-align:super}.mw-parser-output .frac .den{vertical-align:sub}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}12 has special forms).
