Question

Which of the following is the most stable diazonium salt ? (A) C6H5CH2N+2X- (B) CH3 N+2X- (C) CH3CH2N+2X- (D) C6H5N+2X-

Tardigrade Admin · Accepted Answer

C 6 H 5 CH 2 N 2+ X -, CH 3 N 2+ X- and CH 3 CH 2 N 2+ X- are primary amine diazonium salts which are readily decomposed and liberate N 2 gas but C 6 H 5 N 2+ X - is an aryl diazonium salt which is stabilised by resonance of benzene ring which is directly attached with nitrogen.
