Matching compounds with their identifying reagents:

| Compound | Identifying reagent | Reasoning |
|---|---|---|
| Lysine | Ninhydrin (q) | Ninhydrin gives purple (Ruhemann's purple) with -amino acids; lysine is an amino acid |
| Furfural | 1-naphthol (p) | Furfural (an aldehyde from pentoses) reacts with 1-naphthol in Molisch's test to give a purple ring; also used in Tollens' test for furfural identification |
| Benzyl alcohol | Ceric ammonium nitrate (s) | CAN test detects –OH groups (alcoho
