Question

Arrange the following compounds in increasing reactivity with $C{H}_{3}ONa$.

• A. $I<II<III$
• B. $III<II<I$
• C. $II<III<I$
• D. $I<III<II$

Answer 1

The correct option is D $I<III<II$

Nucleophilic substitution will take place more readily where $\delta +$ charge is more or centre having less electron density.
$-N{O}_2$ is strong electron withdrawing group. It show -M effect when present at ortho or para position. It only exhibits -I effect at meta position.
Hence the reactivity follows the order:
