Explain Question :

The problem asks to match substituents on a benzene ring with the type of electronic effects (resonance and inductive) they exhibit.

Concept :

This question is based on Resonance effect ( ± R ), Inductive effect ( ± I)

Solution :

(A) –NO₂: Strong –R effect and –I effect. → (P, S)

(B) –O⁻: Shows +I effect but also +R effect. → (Q, R)

(C) –OCH₃: Shows +R effect and weak –I effect. → (Q, S)

(D) –C≡N: Shows –R effect and –I effect. → (P, S)

Thus, the correct matching is: (A) –P,S ; (B) –Q,R ; (C) –Q,S ; (D) –P,S

List - I	List - II
(A) $- NO_{2}$	(P) - R effect
(B) $- O^{-}$	(Q) +R effect
(C) $- O - CH_{3}$	(R) + I effect
(D) $- C \equiv N$	(S) - I effect
