Why Does Benzene Have a Much Higher Boiling Point (80

question 69

Multiple Choice

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 has fewer hydrogens than hexane.
• B)Benzene is much more polar than hexane which enhances the attractive forces between molecules and raises the boiling point.
• C)Benzene is planar and has delocalized electron density which increases the attractive forces between molecules and raises the boiling point.
• D)Hexane has more Kekulé structures than benzene.
• E)Benzene can covalently bond to another benzene molecule which increases its boiling point.
