Chemical formula of methylbenzene (toluene) = C6H5CH3 (i) Boiling point (liquid to gas) When compared to benzene, in the liquid state, methylbenzene forms stronger intermolecular forces of attraction due to its larger molecular size. Next, the structures are needed. The key difference between benzene and toluene is their structure; toluene has a methyl group attached to the benzene ring while benzene has no methyl groups attached.. Benzene and Toluene are two aromatic compounds having a slight difference between them in their structure. It is a colorless liquid with an aromatic odor.
