Arrange the following in the correct order of reactivity towards nucleophilic substitution reaction.
I. 1-chloro-2-nitrobenzene
II. Chlorobenzene
III. 1-chloro-3-nitrobenzene
- A II > I > III
- B III > I > II
- C I > III > II
- D II > III > I
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…
