The longest hydrocarbons have very high boiling points. They leave the column as a hot liquid called bitumen. Shorter hydrocarbon molecules have weaker intermolecular forces and lower boiling points.

Crude oil comes into a refinery and goes into what is called a crude distillation unit. “There, there is the distillation column and products come out from the column at various levels.
