  2. Octane - Wikipedia

    en.wikipedia.org/wiki/Octane

    Octane is a hydrocarbon and also an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3.Octane has many structural isomers that differ by the location of branching in the carbon chain.

  3. Alkane - Wikipedia

    en.wikipedia.org/wiki/Alkane

    In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. [1] Alkanes have the general chemical formula C n H 2n+2.

    The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [ 1 ] [ 2 ] Number of C atoms

  5. Neopentane - Wikipedia

    en.wikipedia.org/wiki/Neopentane

    Neopentane is the simplest alkane with a quaternary carbon, and has achiral tetrahedral symmetry. It is one of the three structural isomers with the molecular formula C 5 H 12 , the other two being n-pentane and isopentane. Out of these three, it is the only one to be a gas at standard conditions; the others are liquids.

    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.

  8. Heptane - Wikipedia

    en.wikipedia.org/wiki/Heptane

    Heptane or n-heptane is the straight-chain alkane with the chemical formula H 3 C(CH 2) 5 CH 3 or C 7 H 16.When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale (the 100 point is 100% iso-octane).

  9. 2-Methylheptane - Wikipedia

    en.wikipedia.org/wiki/2-Methylheptane

    2-Methylheptane is a branched-chain alkane and an isomer of octane. It is an heptane molecule with a methyl group attached to its second atom. It is a flammable colorless liquid used as fuel. [2] If the standard definition of the prefix "iso-" is strictly used then 2-methylheptane can be called "Isooctane".
