    Numerous organic compounds have other common names, often originating in historical source material thereof. The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid.

  3. Pentane - Wikipedia

    en.wikipedia.org/wiki/Pentane

    Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...

    There is also one compound of n-simplices in n-dimensional space provided that n is one less than a power of two, and also two compounds (one of n-cubes and a dual one of n-orthoplexes) in n-dimensional space if n is a power of two. The Coxeter notation for these compounds are (using α n = {3 n−1}, β n = {3 n−2,4}, γ n = {4,3 n−2}):

  5. 2-Methylpentane - Wikipedia

    en.wikipedia.org/wiki/2-Methylpentane

    2-Methylpentane, trivially known as isohexane, is a branched-chain alkane with the molecular formula C 6 H 14. It is a structural isomer of hexane composed of a methyl group bonded to the second carbon atom in a pentane chain.

    The longest possible main alkane chain is used; therefore 3-ethyl-4-methylhexane instead of 2,3-diethylpentane, even though these describe equivalent structures. The di-, tri- etc. prefixes are ignored for the purpose of alphabetical ordering of side chains (e.g. 3-ethyl-2,4-dimethylpentane, not 2,4-dimethyl-3-ethylpentane).

  7. 2,3-Dimethylpentane - Wikipedia

    en.wikipedia.org/wiki/2,3-Dimethylpentane

    The optical center is the middle carbon of the pentane backbone, which is connected to one hydrogen atom, one methyl group, one ethyl group – C 2 H 5, and one isopropyl group – CH(CH 3) 2. The two enantiomers are denoted (3R)-2,3-dimethylpentane and (3S)-2,3-dimethylpentane (the other simplest chiral alkane is its structural isomer 3 ...

    It is of similar structure to the isomeric 2-methylpentane, which has the methyl group located on the second carbon of the pentane chain. As of early 1990s, it was present in American [3] and European [4] gasoline in small amounts, and by 2011 its share in US gas varied between 1.5 and 6% [5] It has close research and motor octane numbers of 74 ...
