Vedclass · Answer

(A) The given reaction is the $Carbylamine$ reaction,which is a characteristic test for primary amines. In this reaction,a primary amine reacts with chloroform $(CHCl_3)$ and an alcoholic base $(KOH)$ to form an isocyanide (carbylamine),which has an unpleasant odor. The reaction is: $CH_3NH_2 + CHCl_3 + 3KOH \rightarrow CH_3NC + 3KCl + 3H_2O$. The product $CH_3NC$ is methyl isocyanide,which can be represented as $CH_3-N^+ \equiv C^-$. Therefore,the correct option is $A$.
