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

Options

A. deactivates the ring by inductive effect
B. activates the ring by inductive effect
C. decreases the charge density at ortho and para position of the ring relative to meta position by resonance
D. increases the charge density at meta position relative to the ortho and para positions of the ring by resonance

Answer

A, C

Explanation

Nitro group by virtue of -I-effect withdraw electrons from the ring and increase the charge and destabilise carbocation

In ortho, para-attack of electrqhile on nitrobenzene, we are getting two structures (A) and (B) in which positive charge is appearing on the carbon atom directly attached to the nitro group.
As nitro group is electron withdrawing by nature it decreases the stability of such product and hence meta attact is more feasible when electron withbrawing substituents are attached.
