Question

Consider the following statements:
Phenyl diazonium salts form azo dye with
I. aniline
II. Phenol
III. N, N - dimethyl aniline
IV. Anisole (methoxybenzene)
The correct statements is
A. II, III and IV are correct
B. I, III and IV are correct
C. I, II and IV are correct
D. I, II and III are correct

Answer 1

`Phoverset(+)(N)-=N` is a weak electrophile that undergoes diazocoupling only with rings activated by -OH, -`NH_(2)`, -NHR or `NR_(2)`. The ring is not sufficiently activated by `-OCH_(3)` and hence, anisole does not form azodye.
