Reaction with phenol

Vedclass · Answer

(A) The coupling reaction of benzene diazonium chloride with phenol involves the retention of the $-N=N-$ group,forming an azo dye ($p$-hydroxyazobenzene). In other reactions like reduction with phosphinic acid $(H_3PO_2)$,hydrolysis with dilute $H_2SO_4$,or the Sandmeyer reaction with $HCl/Cu$,the diazonium group is replaced by other groups ($-H$,$-OH$,or $-Cl$ respectively),leading to the loss of the diazonium group. Therefore,the correct option is $A$.

Which of the following reactions of a diazonium salt involves the retention of the diazonium group?
