Vedclass · Answer

(D) The reaction of $methyl$ $iodide$ $(CH_3I)$ with $ammonia$ $(NH_3)$ is a nucleophilic substitution reaction known as $Hofmann$ $ammonolysis$.Since the primary amine $(CH_3NH_2)$ formed is more nucleophilic than $ammonia$,it further reacts with $CH_3I$ to form secondary and tertiary amines.Therefore,the reaction proceeds as follows:$CH_3I + NH_3 \rightarrow CH_3NH_2 + HI$$CH_3NH_2 + CH_3I \rightarrow (CH_3)_2NH + HI$$(CH_3)_2NH + CH_3I \rightarrow (CH_3)_3N + HI$Thus,a mixture of primary,secondary,and tertiary amines is obtained.
