What is a Hydrocarbon?
Crude oil is a mixture of substances which are mostly hydrocarbons.
A hydrocarbon is a compound containing hydrogen and carbon only.
Remember the above sentence, you will probably

Do not forget the word only at the end!
oil is a mixture of

the different hydrocarbons will have different boiling points.
A sample of crude oil will therefore have a range of boiling
and the mixture can be separated by fractional distillation.
