2 of 13
What are most of the hydrocarbons?
Alkanes
3 of 13
What is the first step of fractional distillations?
The crude oil is heated until it evaporates
4 of 13
What is the second step of fractional distillation?
The vapour moves up the fractionating column

What is the third step of fractional distillation?
Shorter hydrocarbon molecules can reach the top of the fractionating column before they condense and are collected
