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)
The most stable carbocation from the following is:
Consider the following sequence of reactions : 
Molar mass of the product formed (A) is ______ g mol\(^{-1}\).
0.01 mole of an organic compound (X) containing 10% hydrogen, on complete combustion, produced 0.9 g H₂O. Molar mass of (X) is ___________g mol\(^{-1}\).
