Aromatic Compounds

Historically, the term 'aromatic' originally referred to the smell of selected compounds that later were found to contain benzene or fused benzene rings in the structure. In a structural sense, it designates compounds that, in accordance with the theory of Huckel, have a cyclic, delocalized (4n+2) pi-electron system. This includes arenes and their substitution products (e.g., benzene, naphthalene, toluene). The term has been generalized to include aromatic heterocyclic structures, such as thioph (source : )
