The typical reaction of benzene and other aromatic compounds are electrophilic substitution. Presence of electron donating group activates the ring towards electrophilic substitution, while presence of electron withdrawing group deactivates the ring towards electrophilic substituion but at the same time activates the ring towards nucleophilic subsituion. Some groups are predominantly meta-directing and all of these are deactivating. Except halogen, most of the `o-`and`p-`directing groups are activating groups.
