What is the correct order of boiling points of the following compounds ? 1) butanol 2)butanal 3)butanoic acid
Boiling points depends on strength of intermolecular interaction. In case of butanol and butanoic acid there is H bonding which is a stronger intermolecular attractive force. Further butanoic acid remain in dimeric form so there is more extent of H bonding. So order of boiling point is butanoic acid > butanol > butanal.
