Benzene, C 6 H 6, is the simplest aromatic hydrocarbon and was recognized as the first aromatic hydrocarbon, with the nature of its bonding first being recognized by Kekule kekulÃ© in the 19th. Century each carbon atom in the hexagonal cycle has four electrons to. shareey aromatic hydrocarbons of commercial interest are benzene, toluene, ortho-xylene and para-xylene.
