Gasoline is a mixture composed primarily of
hydrocarbons such as isooctane, which is also known as
2,2,4-trimethylpentane.
Gasoline is assigned a number called an octane
rating. Gasoline with an octane rating of 87 performs
the same as a mixture that consists of 87% isooctane
and 13% heptane.
An alternative fuel, E-85, can be used in some
automobiles. This fuel is a mixture of 85% ethanol and
15% gasoline.
