Question

Contrasting with primary amines, what exact chemical observation is observed when a pure secondary ($2^\circ$) amine is thoroughly subjected to the identical Hinsberg's test?

Prashant Kotian · Accepted Answer

Correct answer: B. A amine reacts successfully with Hinsberg's reagent, generating an N,N-dialkylbenzenesulphonamide. However, because the nitrogen atom is fully alkylated, it totally lacks any remaining acidic protons. Consequently, it cannot react with the strong base and rigorously remains as a water-insoluble solid.
