Question

explain why polar molecules have higher boiling points

Answer 1

Substances with hydrogen bonding, an intermolecular force, will have much higher melting and boiling points than those that haveordinary dipole-dipole intramolecular forces. Non-polar molecules have the lowest melting andboiling points, because they are held together by the weak van der Waals forces.

hope it help....

Answer 2

this is due to high force of attraction
