In conclusion aromaticity is characterized by stability while antiaromaticity is characterized by instability. Aromatic compounds are characterized by substitution reaction such as nitration, alkylation e.t.c. They possess double bond but will never undergo addition reaction due to their stability. The scope of aromaticity is beyond this topic given, for clear understanding, one must consult higher materials.
