Vedclass · Answer

(B) The carbylamine test is a chemical test for the detection of primary amines. In this reaction,a primary amine is heated with chloroform $(CHCl_3)$ and an alcoholic solution of potassium hydroxide $(KOH)$. The reaction produces an isocyanide (also known as a carbylamine),which has a characteristic foul smell. The general reaction is: $R-NH_2 + CHCl_3 + 3KOH \rightarrow R-NC + 3KCl + 3H_2O$. Among the given options,the general product is an isocyanide $(R-NC)$.
