Question

Q.(a) only primary amine gives carbyl amine reaction. why​

Answer 1

Answer:

As it is only effective for primary amines, the carbylamine reaction can be used as a chemical test for their presence. ... In this reaction, the analyte is heated with alcoholic potassium hydroxide and chloroform. If a primary amine is present, the isocyanide (carbylamine) is formed, as indicated by a foul odour.

Answer 2

Answer :-

In secondary amine and tertiary amine, nitrogen does not hold more hydrogen atoms, and also, a sterically highly unstable product will be formed if the secondary amines and tertiary amines would be reacted. And notably, alkyl isocyanides are the compounds that exhibit unpleasant smelling. Hence, we use this test for the detection of only the primary amines.
