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.

 

Answers (1)

The answer is the option (i) deactivates the ring by inducive effect & (iii) decreases the charge density at ortho and para position of the ring relative to meta position by resonance.

Explanation: Meta position is attacked by an electrophile. Due to the -I effect nitro group deactivates the benzene ring and decreases electron density at ortho and para positions than meta position.
