Question

Which of the following steps is not correct in the mechanism of electrophilic substitution of benzene?

• A. Generation of electrophilie like $\mathrm { X } ^ { + } , \mathrm { R } ^ { + } \mathrm { RC } ^ { + } \mathrm { O } , \mathrm { NO } _ { 2 } ^ { + }$etc
• B. Attack of electrphile resulting in the formation of arenium ion in which one of the carbon is hybridized.
• C. Addition of proton on benzene ring to give carbocation
• D. Removal proton from carbon atom to restore aromatic character,.

Answer 1

Answer: (C)

Addition of proton on benzene ring to give carbocation

Answer 2

: Arenium ion is formed as intermediate by the attack of electrophile not by addition of proton. Proton is substituted by electrophile.
