Crude oil is a mixture of hydrocarbons. These are separated into useful products, such as fuels, using a process called fractional distillation. The demand for short hydrocarbon molecules is greater than their supply in crude oil, so a reaction called cracking is used.Cracking converts long alkane molecules into shorter alkanes and alkenes, which are more useful. The exploitation of oil can damage the environment-for example, through oil spills.he demand for short hydrocarbon molecules is greater than their supply in crude oil, so a reaction called cracking is used.
