1.	Which of the following steps is not correct in the mechanism of electrophilic substitution of benzene?
Answer» Generation of electrophile LIKE `X^(+),R^(+),RC^(+)O,NO_(2)^(+),`etc. Attack of electrophile RESULTING in the formation of arenium ion in which ONE of the carbon is `sp^(3)` hybridised. Addition of PROTON on benzene ring to give carbocation. Removal of proton from `sp^(3)` carbon atom to restore aromatic character. Solution :Arenium ion is formed as intermediate by the attack of electrophile not by addition of proton. Proton is substituted by electrophile.
