Question

p-toluidine and benzyl amine can be distinguished by

(a) Sandmeyer's reaction 

(b) Dye test

(c) Molisch test 

(d) Gattermann reaction

Answer 1

Correct Option (b) Dye test

Explanation:

contains amino group directly attached to benzene ring. thus undergo diazotisation reaction and give red dye. In benzyl amine (C₆H₅CH₂NH₂) the amino group is not directly attached to benzene ring, hence it will not undergo diazotisation reaction.
