Question

In an electrophilic substitution reaction of nitrobenzene, the presence of nitro group:

(i) Deactivates the ring by inductive effect.

(ii) Activates the ring by inductive effect.

(iii) Decreases the charge density at ortho and para position of the ring relative to meta position by resonance.

(iv) Increases the charge density at meta position relative to the ortho and para positions of the ring by resonance.

Short Note

Solution

(i) Deactivates the ring by inductive effect.

(iii) Decreases the charge density at ortho and para position of the ring relative to meta position by resonance.

Explanation:

The nitro group strongly deactivate the ring due to the -R effect and -I effect
