Consider the following statements Phenyl diazonium forms azodye with 1 . aniline 2 . phenol 3 . N, N-dimethylaniline 4 . anisole (methoxybenzene)

Options

  1. A2 , 3 and 4 are correct
  2. B1 , 3 and 4 are correct
  3. C1 , 2 and 4 are correct
  4. D1 , 2 and 3 are correct

Correct answer

D. 1 , 2 and 3 are correct

Step-by-step solution

P h N + ≡ N is a weak electrophile that undergoes diazocoupling with rings activated by - O H , - N H 2 , N H R or - N R 2 . The ring is not sufficiently activated by - O C H 3 and hence, anisole does not form azodye.
