Vedclass · Answer

(A) The molecular formula $(C_3H_9N)$ corresponds to a primary amine. When treated with nitrous acid $(HNO_2)$,primary aliphatic amines evolve $N_2$ gas and form an alcohol. The carbylamine reaction (warming with $CHCl_3$ and $KOH$) is a characteristic test for primary amines,forming an isocyanide $(C)$. Reduction of the isocyanide $(CH_3)_2CH-NC$ gives isopropylmethylamine $(CH_3)_2CH-NH-CH_3$. Therefore,$(A)$ is isopropylamine,$(CH_3)_2CH-NH_2$.

An organic compound $(C_3H_9N)$ $(A)$,when treated with nitrous acid,gave an alcohol and $N_2$ gas was evolved. $(A)$ on warming with $CHCl_3$ and caustic potash gave $(C)$ which on reduction gave isopropylmethylamine. Predict the structure of $(A)$.
