Why does benzene have a much higher boiling point (80。c) than hexane (69。c), even though they have the same number of carbons? A) Benzene is much more polar than hexane which enhances the attractive forces between molecules and raises the boiling point. B) Benzene has fewer hydrogens than hexane. C) Benzene is planar and has delocalized electron density which increases the attractive forces between molecules and raises the boiling point. D) Benzene can covalently bond to another benzene molecule which...
