Fractional Distillation

Fractional distillation is a continuous process that separates the different lengths of hydrocarbons
in crude oil, using their differing volatility. The crude oil is vaporised and travels up the column. It
is separated into fractions that each has a specific boiling point range.

Alkanes Saturated hydrocarbons with a general e.g. Butane
formula of C
nH2n+2 which means they are all

members of a homologous series

Alkenes Unsaturated hydrocarbons with at least one e.g. Ethene
double C=C bond. They have the general

formula Cn

Cycloalkanes Saturated hydrocarbons with a general e.g cyclohexane…
