Vedclass · Answer

(D) The carbylamine test is a characteristic reaction given only by primary $(1^{\circ})$ amines,whether aliphatic or aromatic. In this reaction,the primary amine reacts with chloroform $(CHCl_3)$ and alcoholic potassium hydroxide $(KOH)$ to form an isocyanide (carbylamine),which has a foul smell. $R-NH_2 + CHCl_3 + 3KOH \rightarrow R-NC + 3KCl + 3H_2O$. Among the given options: $A$. Ethylamine $(CH_3CH_2NH_2)$ is a primary amine. $B$. Sec. butylamine $(CH_3CH_2CH(NH_2)CH_3)$ is a primary amine. $C$. Isopropylamine $((CH_3)_2CHNH_2)$ is a primary amine. $D$. Dimethylamine $((CH_3)_2NH)$ is a secondary $(2^{\circ})$ amine. Therefore,Dimethylamine does not give the carbylamine test.
