Why do alcohols have higher boiling points than haloalkanes of the same molecular mass?

Text Solution

Verified by Experts

The boiling points of alcohols are higher than the corresponding halonnes of the sume molecular mage. This is mainly due to strong intermolecular hydrogen bonding between alcohol molecules. Because of hydrogen bonding in alcohols, energy has to be supplied to overcome the force of attraction and consequently boiling points are high No such hydrogen bonding waists in haloalkanes. For example, b.pt. of `CH_(2)OH` while that of `CH_(3)CI` only 249 K.
