Question
Which of the following steps is not correct in the mechanism of electrophilic substitution of benzene?
A.
Generation of electrophile like $${X^ + },{R^ + },NO_2^ + ,$$ etc.
B.
Attack of electrophile resulting in the formation of arenium ion in which one of the carbon is $$s{p^3}$$ hybridised.
C.
Addition of proton on benzene ring to give carbocation.
D.
Removal of proton from $$s{p^3}$$ carbon atom to restore aromatic character.
Answer :
Addition of proton on benzene ring to give carbocation.
Solution :
Arenium ion is formed as intermediate by the attack of electrophile not by addition of proton. Proton is substituted by electrophile.
