Solution:

Due to dipole-dipole interactions the boiling point of alkyl halide is higher as compared to corresponding alkanes. Alkanes, being non polar, have weak van der walls forces of attraction. In alkyl halides, bond is polar. Hence, strong dipoledipole interactions are present. Greater is the strength of intermolecular forces, higher is the boiling point.
