II. Chlorobenzene
III. 1-chloro-3-nitrobenzene

  1. A II > I > III
  2. B III > I > II
  3. C I > III > II
  4. D II > III > I
Verified Solution

Answer & Solution

Correct Answer

(C) I > III > II

Step-by-step Solution

Detailed explanation

Presence of \(-\mathrm{NO}_2\) group will favour chlorobenzene towards nucleophilic substitution, \(\operatorname{ArS}_{\mathrm{N}} 2\) (via addition elimination mechanism) \(-R\) effect of \(-\mathrm{NO}_2\) at ortho position (I) will favour the reaction most in comparison to…
