Why do alcohols have higher boiling points than halo-alkanes of the same molecular mass ?

Text Solution

Verified by Experts

The inter-molecular forces of attraction between molecule of alcohols are strong H-bonding, on the other hand, the intermolecular force of attraction between molecules of haloalkanes are comparatively weaker dipole-dipole interactions. Due to stronger intermolecular forces of attraction in alcohols, alcohols liave higher boiling point than haloalkanes of comparable molecular mass.
