Vedclass · Answer

(B) The given reaction is the $Carbylamine$ reaction,which is a characteristic test for primary amines. When an aliphatic or aromatic primary amine is heated with chloroform $(CHCl_3)$ and alcoholic potassium hydroxide $(KOH)$,an isocyanide (or carbylamine) is formed. The reaction is: $CH_3-CH_2-NH_2 + CHCl_3 + 3KOH \rightarrow CH_3-CH_2-NC + 3KCl + 3H_2O$. The product formed is ethyl isocyanide $(CH_3-CH_2-NC)$.

$CH_3-CH_2-NH_2 \xrightarrow{CHCl_3, KOH} \text{Product}$
