Identify the correct statements : The presence of -NO2 group in benzene ring Choose the correct answer from the options given below :

  1. A and D Only
  2. B and D Only
  3. C and A Only
  4. B and C Only

Answer

(4) B and C Only

Solution

-NO2 is strongly electron-withdrawing (−I and −R effects).

It decreases the electron density of the ring (especially at o- and p-positions), so the ring is deactivated towards electrophilic substitution B true, A false.

In nucleophilic substitution, an o-/p-NO2 group stabilises the negatively charged intermediate (carbanion) by resonance, so the ring is activated towards nucleophilic substitution (as per NCERT, o/p-nitrochlorobenzenes react easily with OH-) C true, D false.

B and C only

Answer: (4)
