Match List-I with List-II. List-I Functional group (detection) A. Unsaturation (Baeyer's test) B. Alcoholic group (Ceric ammonium nitrate test) C. Aldehyde group (Tollen's reagent) D. Phenolic group (FeCl3 test) List-II Change observed during detection I. Red colour Appears II. Silver mirror appears III. Violet colour appears IV. Discharge of pink colour Choose the correct answer from the options given below:

1. A-III, B-IV, C-II, D-I
2. A-III, B-IV, C-I, D-II
3. A-IV, B-I, C-II, D-III
4. A-IV, B-III, C-II, D-I

Correct answer: A-IV, B-I, C-II, D-III

Solution

The correct option matches each functional group with its corresponding detection change: Unsaturation is indicated by a discharge of pink color (IV), the alcoholic group shows a red color with Ceric ammonium nitrate (I), the aldehyde group produces a silver mirror with Tollen's reagent (II), and the phenolic group gives a violet color with FeCl3 (III).
