Incorrect! Answer:
Primary amines (aliphatic/aromatic)
- Reactants: Aliphatic or aromatic primary amine, Chloroform (CHCl3), and alcoholic Potassium Hydroxide (KOH).
- Reaction: R−NH2+CHCl3+3KOH→R−NC(Isocyanide)+3KCl+3H2O.
- Observation: The product is an alkyl or aryl isocyanide (carbylamine), which has an extremely offensive and characteristic foul smell.
- 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.
