This article focus to Discuss on Electrophilic Aromatic Substitution Reactions. Although aromatic compounds have a number of double bonds, these compounds tend not to undergo addition reactions. Their lack of reactivity toward addition reactions is due to the great stability of the ring systems that originate from complete π electron delocalization. Aromatic compounds react by electrophilic fragrant substitution reactions, in that your aromaticity of the ring system is preserved.
