So, 1-butanol has a higher boiling point. Sample Solution. It smells sharp and sweet, like butterscotch and acetone mixed. 1.Butanoic acid has stronger intermolecular forces (hydrogen bonding) because it has two highly electronegative oxygen atoms in its structure, whereas butan-1-ol has only one.Therefore the acid molecules can form stronger bonds between neighbouring molecules. If the BP of butanone is higher than butanol, my guess would be that the bond holding the molecules together is stronger.
