Vedclass · Answer

(D) This reaction is known as the $Carbylamine$ test,which is used to identify primary amines.When an aliphatic primary amine $(R-NH_2)$ is heated with chloroform $(CHCl_3)$ and ethanolic potassium hydroxide $(KOH)$,it forms an alkyl isocyanide $(R-NC)$,which has a foul smell.The chemical equation is: $R-NH_2 + CHCl_3 + 3KOH (alc.) \rightarrow R-NC + 3KCl + 3H_2O$.This reaction involves the formation of a dichlorocarbene intermediate $(:CCl_2)$.

On heating an aliphatic primary amine with chloroform and ethanolic potassium hydroxide,the organic compound formed is:
