1. **Reactants**: Aliphatic or aromatic **primary amine**, Chloroform ($CHCl_3$), and alcoholic Potassium Hydroxide ($KOH$).
2. **Reaction**: $R-NH_2 + CHCl_3 + 3KOH 	o R-NC (	ext{Isocyanide}) + 3KCl + 3H_2O$.
3. **Observation**: The product is an alkyl or aryl **isocyanide (carbylamine)**, which has an extremely offensive and characteristic **foul smell**.
4. **Specificity**: Secondary and tertiary amines do not have two replaceable hydrogen atoms on the nitrogen and thus do not undergo this reaction. This makes it a diagnostic test for primary amines.
