Match the LIST-I with LIST-II

Choose the correct answer from the options given below:
Matching Analysis:
- A: Sodium bicarbonate solution - Reacts with carboxylic acids (II) to produce effervescence (CO2)
- B: Neutral ferric chloride - Gives colored complex with phenolic -OH (III)
- C: Ceric ammonium nitrate - Red color with alcoholic -OH (IV)
- D: Alkaline KMnO4 - Decolorizes with double bonds (I)
Correct Mapping:
- A → II (Carboxylic acid)
- B → III (Phenolic -OH)
- C → IV (Alcoholic -OH)
- D → I (Double bond)
