Aromatics are a broad group of compounds that include benzene and compounds that are chemically similar to benzene. Some of these substances do not even seem to be similar to benzene. Unlike alkenes and alkynes, benzene and other aromatic compounds do not show a tendency to increase reactions, but participate in substitution reactions, which is one of the hallmarks of these substances.

If the operating groups are on If rings are placed, they will affect the reactivity of the ring. The reactivity of the factors attached to the ring is also affected by the aromatic part.
