RankGuru · Accepted Answer

The **Carbylamine Test** (or Isocyanide Test) is extremely specific for **Primary ($1^\circ$) Amines**, both aliphatic and aromatic.
- Reaction: $R-NH_2 + CHCl_3 + 3KOH(alc) \xrightarrow{\Delta} R-NC + 3KCl + 3H_2O$
- Observation: The formation of an **Alkyl Isocyanide ($R-NC$)** which has an intensely **foul or unpleasant smell**.
- Secondary and tertiary amines do not contain the necessary two hydrogen atoms on the nitrogen to form the isocyanide and thus do not give this test.
