Question

An amine X (C4H11N) on heating with CHCl3 in ethanolic KOH forms a foul-smelling substance. Product of other amine Y (C4H11N) and benzenesulphonyl chloride is insoluble in alkali. What are X and Y respectively?

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Use Carbylamine test to identify primary amines; secondary/tertiary amines give no test reaction.

Answer 1

The Correct Option is B

X is primary amine → reacts with CHCl$_3$/KOH (Carbylamine test) → foul smell. Y is secondary → no reaction with Carbylamine test; forms sulphonamide → insoluble in alkali.
