Solution
Correct Answer:
Isocyanide (foul smell)
- Reaction: Aliphatic or aromatic primary amine + CHCl3+3KOHΔR−NC+3KCl+3H2O.
- Characteristic: The product is an alkyl or aryl isocyanide (also called a carbylamine).
- Observation: Isocyanides have a highly unpleasant, offensive odor (described as a 'foul smell').
- Diagnostic Value: Since only primary amines (1∘) undergo this reaction, it is used to distinguish them from secondary (2∘) and tertiary (3∘) amines.
This easy difficulty chemistry question is from the chapter nitrogen organics, covering the topic of carbylamine test. It appeared in the 2025 exam.
