Benzenediazonium chloride and $p$-(dimethylamino)azobenzene

Vedclass · Answer

(A) The reaction of aniline with $NaNO_2$ and $HCl$ at $273-278 \ K$ is a diazotization reaction,which produces benzenediazonium chloride as the major product $(X)$.Benzenediazonium chloride then undergoes an electrophilic aromatic substitution reaction (coupling reaction) with $N,N$-dimethylaniline. Since the $-N(CH_3)_2$ group is a strong activating group and is ortho/para-directing,the coupling occurs primarily at the para-position due to steric hindrance at the ortho-position.Therefore,the major product $(Y)$ is $p$-(dimethylamino)azobenzene.

Considering the above reaction,$X$ and $Y$ respectively are
