In organic chemistry, an alkane, or paraffin, 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–

Octane is a hydrocarbon and also an alkane with the chemical formula C8H18, and the condensed structural formula CH36CH3. Octane has many structural isomers that differ by the location of branching in

…where n = 1 (sometimes called the parent molecule), to arbitrarily large and complex molecules, like hexacontane (C60H122) or 4-methyl-5-(1-methylethyl) octane, an isomer of dodecane (C12H26). The International Union of Pure and Applied Chemistry (IUPAC) defines alkanes as "acyclic branched or unbranched…
N-octane is the octane isomer that has the longest carbon skeleton. Unlike its constitutional isomers, it has a very low knock resistance.
The octane isomer, iso-octane, is used as one of the standards for octane ratings. It has a rating of 100 by definition.
The octane isomer 2,3,3-Trimethylpentane has an octane rating exceeding 100.
