Solution: Melting and boiling points for benzene, toluene, and phenol.In which substance, benzene or toluene, are the intermolecular forces stronger?

Problem

Benzene is a six carbon ring with alternating double bonds in the sides, each carbon bonded to a single hydrogen.  Benzene has a melting point of 5 degrees celsius and a boiling point of 80 degrees celsius. Toluene is a benzene ring with a methyl group, CH3, attached to one of the carbons instead of a hydrogen.  Toluene has a melting point of -95 degrees celsius and a boiling point of 111 degrees celsius. Phenol is a benzene ring with a hydroxy group, OH, attached to one of the carbons instead of a hydrogen.  Phenol has a melting point of 43 degrees celsius and a boiling point of 182 degrees celsius.
