Reaction Mechanisms - IITPK
www.iitpk.comElectrophilic substitution (SE2) is every common in benzene nucleus (aromatic compounds) in which . π electrons are highly delocalized and an electrophile can attack the region of high electron density. Aromatic electrophilic substitution reactions involve the following 3 steps mechanism : Step-1: The formation of an electrophile. Step-2

www.saplinglearning.com16.4 ELECTROPHILIC AROMATIC SUBSTITUTION REACTIONS OF BENZENE 755 Step 2 Reaction of the benzene p electrons with the electrophile to form a carbocation inter- mediate. (Notice that either of the oxygens can accept the electron pair.) Step 3 Loss of a proton from the carbocation to give a new aromatic compound. Nitration is the usual way that nitro groups are introduced into aromatic rings.
