Question

Arrange the following compounds in decreasing order of coupling with benzenediazonium chloride. (A) IV > I > II > III (B) II > I > IV > III (C) II > IV > I > III (D) II > III > IV >I

Tardigrade Admin · Accepted Answer

Coupling reaction between arenediazonium cation and an aromatic compounds which bear powerful electron- releasing group like - OH ,- NH 2,- NHR, or - NR 2. Hence toluene, having weak electron-releasing - CH 3 group can't couple with diazonium cation.

Q. Arrange the following compounds in decreasing order of coupling with benzenediazonium chloride.

IV > I > II > III

II > I > IV > III

II > IV > I > III

II > III > IV >I

Coupling reaction between arenediazonium cation and an aromatic compounds which bear powerful electron- releasing group like $- O H, - N H_{2}, - N H R$ , or $- N R_{2}$ . Hence toluene, having weak electron-releasing $- C H_{3}$ group can't couple with diazonium cation.

Coupling reaction between arenediazonium cation and an aromatic compounds which bear powerful electron- releasing group like −OH,−NH2​,−NHR, or −NR2​. Hence toluene, having weak electron-releasing −CH3​ group can't couple with diazonium cation.
