The simple answer is molecular dipoles.
Explanation:
Dipoles result from unequal sharing of electronic density in a molecule. And so typically they are observed for molecules in which there are one or more strongly electronegative atoms. And by way of example compare the volatilities of chloromethane, a polar molecule, normal boiling point
In the bulk phase, the dipoles interact to constitute an intermolecular force, that should be expressed in the individual normal boiling points of each molecule.
