Question

The increasing order of reactivity of the following compounds towards aromatic electrophilic substitution reaction is:

• A. D > B > A > C
• B. A < B < C < D
• C. D > A > C > B
• D. B > C > A > D

Answer 1

The correct option is D B > C > A > D

Any factor which increases the electron density on benzene ring increases the rate towards electrophilic substitution reaction.
$-Cl$ despite being $+R$ is ring deactivating due to strong $-I$ Effect.
