Question

Phenol undergoes electrophilic substitution more easily than benzene because

• A. -OH group exhibits +M effect and hence increases the electron density on the o- and p-positions.
• B. oxocation is more stable than the carbocation
• C. both (a) and (b)
• D. -OH group exhibits acidic character

Answer 1

Answer: (C)

High stability of oxonium ion (oxocation) is because here every atom (except $H$ ) has a complete octet of electrons, while in carbocations, carbon bearing positive charge is having six electrons.
