Match the compounds in LIST-I with the observations in LIST-II, and choose the correct option. List-I List-II (I) Aniline (P) Sodium fusion extract of the compound on boiling with FeSO 4 , followed by acidification with conc. H 2 SO 4 , gives Prussian blue color. (II) o-Cresol (Q) Sodium fusion extract of the compound on treatment with sodium nitroprusside gives blood red color. (III) Cysteine (R) Addition of the compound to a saturated solution of NaHCO 3 results in effervescence. (IV) Caprolactam (S) The compound reacts with bromine water to give a white precipitate. (T) Treating the compound with neutral FeCl 3 solution produces violet color.

1. I → P,Q; II → S; III → Q,R; IV → P
2. I → P; II → R,S; III → R; IV → Q,S
3. I → Q,S; II → P,T; III → P; IV → S
4. I → P,S; II → T; III → Q,R; IV → P

Correct answer: I → P,S; II → T; III → Q,R; IV → P
