The boiling point of a halogenoalkane depends mainly on the strength of the van der Waals forces between its molecules. There are also permanent dipole-dipole forces because the carbon-halogen bond is polar.

Boiling point increases as the carbon chain gets longer, because larger molecules have more electrons and a greater surface area of contact, so the van der Waals forces are stronger.
