Vedclass · Answer

(A) The reaction between phenol $(C_6H_5OH)$ and an arenediazonium salt $(ArN_2^+Cl^-)$ in the presence of a base $(OH^-)$ is an electrophilic aromatic substitution reaction known as coupling reaction. In this reaction,the diazonium cation acts as an electrophile and attacks the electron-rich phenol ring. Since the $-OH$ group is ortho/para-directing,the coupling primarily occurs at the para-position to form $p-hydroxyazobenzene$ derivatives $(Ar-N=N-C_6H_4-OH)$.
