Molecule fo gasoline

  1. A stupid question: when we buy gas at the gas station, what is the molecule that makes up the gasoline? (I know there are additives so strictly speaking there is not a single type of molecule but I am wondering about the main constituent).

    Gasoline isn't a pure compound it's a mixture of hydrocarbons typically about 5-10 carbons long, depending on the grade. So it would be C5H12 + C6H14 + C7H16 etc.

    There are also some aromatic hydrocarbons such as toluene and benzene.
  4. Thank you very much mgb_phys
