Solution and Explanation
Step 1: Nature of reaction.
Aliphatic primary amines react with nitrous acid to form alcohols, releasing nitrogen gas.
Step 2: Reaction.
Ethanamine + nitrous acid → Ethanol + N\(_2\) + H\(_2\)O.
Step 3: Conclusion.
Hence ethanamine gives ethanol by reaction with NaNO\(_2\)/HCl.
