Octane is a hydrocarbon an an alkane wi the chemical formula C8H18, an the condensed structural formula CH3(CH2)6CH3. Octane haes mony structural isomers that differ bi the amoont an location o branchin in the carbon chain. Ane o these isomers, 2,2,4-trimethylpentane (isooctane) is uised as ane o the staundart values in the octane ratin scale.
As wi aw law-molecular wicht hydrocarbons, octane an its isomers are very flammable an are components o gasoline (petrol).
