The typical reaction of benzene and other aromatic compounds is electrophilic substitution. Presence of electron donating group activates the ring towards electrophilic substitution, while presence of electron withdrawing group deactivates the ring towards electrophilic substitution but at the same time activates the ring towards nucleophilic substitution. Some groups are predominantly meta directing and all of these are deactivating. Except halogen, most of the o- and p- directing groupsare activating groups. (E.A.S = Electrophilic aromatic substation) Presence of nitro group in benzene ring:

Answer» Deactivates the RING for E.A.S. REACTION Activates the ring for B.A.S. REACTIONS No EFFECT the ring for E.A.S reaction Deactivate the ring for SN reactions SOLUTION :`-NO_2` is meta directing and deactivate the benzene ring
