Vedclass · Answer

(B) The reaction of phenol with benzenediazonium chloride $(C_6H_5N_2^+Cl^-)$ in the presence of a base $(KOH)$ is an electrophilic aromatic substitution reaction known as a coupling reaction.In this reaction,the diazonium cation acts as an electrophile and attacks the electron-rich ring of phenol at the para-position to form $p$-hydroxyazobenzene.Since the question mentions both phenol and aniline,but the diazonium salt is derived from aniline $(C_6H_5N_2^+Cl^-)$,the coupling occurs between the diazonium salt and the phenol to yield $p$-hydroxyazobenzene.
