Explain why propanol has a higher boiling point than hydrocarbon butane ?

Text Solution

Verified by Experts

The molecules of butane are held togetehr by weak van der waals forces of attraction while those of propanol are held together by stronger intermolecular hydrogen bonding.

Therefore, the b.p. of propanol is much higher than that of butene.
