Vedclass · Answer

(B) The reaction of primary amines with $CHCl_3$ and $KOH$ (alcoholic) is known as the carbylamine test,which produces an isocyanide (carbylamine) with a foul smell. $R-NH_2 + CHCl_3 + 3KOH \rightarrow R-NC + 3KCl + 3H_2O$ Secondary and tertiary amines do not undergo this reaction because they lack the necessary hydrogen atoms on the nitrogen atom to form the isocyanide intermediate. Among the given options: $(A)$ Isobutylamine ($CH_3)_2CHCH_2NH_2$ is a primary amine. $(B)$ Diethylamine $(C_2H_5)_2NH$ is a secondary amine. $(C)$ Aniline $C_6H_5NH_2$ is a primary amine. $(D)$ Ethylamine $C_2H_5NH_2$ is a primary amine. Therefore,diethylamine will not give the isocyanide test.

Which of the following compounds will not give isocyanide on reaction with $CHCl_3 + KOH$?
