Why is HI’s boiling point higher?

The boiling point rises from HCl to HI. The increasing intensity of the van der Waals intermolecular forces is due to this trend, which coincides with the number of electrons in the molecules. The HI molecule’s diffuse electron cloud makes for intermolecular interaction that is more successful (i.e. more attractive).
