Which of the following correctly matches the qualitative functional group test with the chemical spe — Practical Organic Chemistry and Purification Chemistry Question

💡 Solution & Explanation

Tollen's test yields a silver mirror of metallic $Ag$. Fehling's test yields a brick-red precipitate of Cuprous Oxide ($Cu_2O$). The Iodoform test yields a pale yellow precipitate of Triiodomethane ($CHI_3$). Hinsberg's test for a secondary ($2^\circ$) amine yields an N,N-dialkylbenzenesulphonamide, which lacks an acidic proton and therefore does NOT form a soluble sodium salt in alkali.
