A) \[N{{O}_{2}}\] makes the ring electron rich at ortho and para positions.
B) \[N{{O}_{2}}\] withdraws \[{{e}^{-}}\] from meta-position.
C) \[N{{O}_{2}}\] donates \[{{e}^{-}}\] at meta-position.
D) \[N{{O}_{2}}\] withdraws \[{{e}^{-}}\] from ortho/para-positions.
Correct Answer: D
Solution :
[d] \[-N{{O}_{2}}\] group withdraws electrons from o- and p-positions and hence activates the -Cl present on that position towards nucleophilic substitution.
