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.
