Assertion : For preparation of phenol from diazonium salt, benzene diazonium hydrogen sulphate is better than benzene diazonium chloride.
Reason : This is an `S_(N)1` reaction so `Cl^(Theta)` may attack phenyl cation, producing some chlorobenzene.

Aniline is an aromatic primary amine.Starting from aniline a number of organic compounds can be prepared.How is the phenol obtained from benzene diazonium chloride?

Arene diazonium salts are more stable than alkanediazonium salts due to dispersal of the positive charge on the benzene ring. Obviously, electron-donating groups favour diazotisation by retarding the decomposition of diazonium salts to phenyl cation. The high reactivity of arenediazonium salts is due to the excellent leaving ability of the diazo group as N_2 gas. Consider the following ions: The reactivity of these ions towards azo coupling reactions under similar conditions is
