Vedclass · Answer

(A) The carbylamine reaction (also known as the isocyanide test) is a chemical test for the detection of primary amines. In this reaction,a primary amine (aliphatic or aromatic) is heated with chloroform $(CHCl_3)$ and an alcoholic solution of potassium hydroxide $(KOH)$. This results in the formation of an isocyanide (carbylamine),which has a foul smell. The general reaction is: $R-NH_2 + CHCl_3 + 3KOH (	ext{alc.}) ightarrow R-NC + 3KCl + 3H_2O$. Therefore,the required reagents are a primary amine and chloroform.

In the carbylamine reaction,hot alcoholic $KOH$ and ...... are required.
