Benzene diazonium chloride undergoes an electrophilic aromatic substitution coupling reaction with p — Amines Chemistry Question

💡 Solution & Explanation

The diazonium cation is a weak electrophile. A mildly basic medium (pH 9-10) accurately converts the phenol into the vastly more nucleophilic phenoxide ion, immensely accelerating the coupling while avoiding the highly basic destruction of the diazonium salt.
