It is any of a large class of organic compounds including
Benzene and compounds that resemble benzene in chemical
Aromatic compounds contain unusually stable
ring structures, often made up of six carbon atoms
arranged hexagonally. Some of the compounds, however
have rings with more or fewer atoms, not necessarily
Furan, for example, has a ring with four
atoms of carbon and one of oxygen. Also two or more
rings can be fused, as in naphthalene.
properties of the class, notably the stability of
the compounds, derived from the fact that aromatic
rings permit the sharing of some electrons by all
the atoms of the ring, which increases the strength
of the bonds.
