Gasoline is the name given to some of the lighter and more volatile portions obtained in the distillation and purification of crude petroleum. It is a very volatile liquid with boiling-point varying from about 35° to 80° C, which consists mainly of a mixture of the hydrocarbons - pentane (C₅H₁₂), liexane (C₆H₁₄), and heptane (C₇H₁₆).
