Why does benzene have a much higher boiling point (80 °C) than hexane (69 °C), even though they have the same number of carbons?

▸ Benzene has fewer hydrogens than hexane.

▸ Benzene is much more polar than hexane which enhances the attractive forces between molecules and raises the boiling point.

▸ Benzene is planar and has delocalized electron density which increases the attractive forces between molecules and raises the boiling point.

▸ Hexane has more Kekulé structures than benzene.

▸ Benzene can covalently bond to another benzene molecule which increases its boiling point.
