Usually, we treat it as hexanes, #C_6H_14#, or as octane, #C_8H_18#.

Explanation:

#"Petrol"# is the term used in the UK and commonwealth countries, #"gasoline"# is the term used in North America. The petrol you buy for your motor is a formulation, and contains several compounds including butane, and even molecules as large as #C_10# and #C_12#; alkanes, olefins, and some ethers are present. The presence of the smaller alkanes gives petrol a low flash point, and if you ever see someone smoking at a gas station you walk away.......
