Carboxylic acids have higher boiling points than aldehydes, ketones and even alcohols of comparable molecular mass. It is due to their _________.
Carboxylic acids have higher boiling points than aldehyde, ketones and even alcohols of comparable molecular mass because of the extent of intermolecular-hydrogen bonding with water, due to which they exist as associated molecules. The hydrogen bonds are not completely broken in the vapour state.
