Question

Ceric ammonium nitrate and $CHC{l}_3/alc.KOH$ are used for the identification of functional groups present in _________ and ________ respectively.

• A. alcohol, amine
• B. amine, alcohol
• C. alcohol, phenol
• D. amine, phenol

Answer 1

The correct option is A alcohol, amine

Carbylamine reaction is used for test of primary amines.
In this reaction, the primary amine is heated with $CHC{l}_3$ and KOH to form isocyanide. Formation of isocynaide is indicated by the obnoxious smell. This confirms the presence of primary amino group.
The reaction of the process is:
$R-N{H}_2+CHC{l}_3+3KOH\to RNC+3KCl+3H_{2}O$

Alcohol gives a positive test with ceric ammonium nitrate.
Alcohol on reacting with ceric ammonium nitrate gives red colour solution.
Hence, option (a) is correct.
