Phenyl diazonium salts form azo dye with(1) Aniline(2) Phenol(3) N, N...
PhN+ ≡ N is a weak electrophile that undergoes diazocoupling only with rings activated by −OH,−NH2,−NHR or−NR2. The ring is not sufficiently activated by -OCH3 and hence, anisole does not form azodye.

Phenyl diazonium salts form azo dye with(1) Aniline(2) Phenol(3) N, N...
Phenyl diazonium salts and formation of azo dyes:
Phenyl diazonium salts are important intermediates in the synthesis of azo dyes, which are characterized by the presence of an azo group (-N=N-) linking two aromatic rings. The reaction involves the coupling of phenyl diazonium salts with various compounds to form azo dyes.
Correct statements:
Aniline (1):
Aniline can react with phenyl diazonium salts to form azo dyes. This reaction is commonly used in organic chemistry for the synthesis of azo compounds.
Phenol (2):
Phenol can also undergo coupling with phenyl diazonium salts to produce azo dyes. This reaction is another example of the versatility of diazonium salts in organic synthesis.
N, N–dimethylaniline (3):
N, N–dimethylaniline is another compound that can react with phenyl diazonium salts to form azo dyes. This highlights the broad scope of diazonium salt chemistry.
Anisole (methoxybenzene) (4):
Anisole, also known as methoxybenzene, is a compound that can participate in the formation of azo dyes when coupled with phenyl diazonium salts. This reaction demonstrates the flexibility of diazonium salts in forming various azo compounds.
Therefore, the correct statements are 1, 2, and 3, as aniline, phenol, and N, N–dimethylaniline can all form azo dyes with phenyl diazonium salts.
