Match the LIST-I with LIST-II

LIST-I (Reagent)LIST-II (Functional Group detected)
A. Sodium bicarbonate solutionI. double bond/unsaturation
B. Neutral ferric chlorideII. carboxylic acid
C. ceric ammonium nitrateIII. phenolic - OH
D. alkaline KMnO4KMnO_4KMnO4​4IV. alcoholic - OH

Choose the correct answer from the options given below:

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

Correct answer: D

  1. We match each reagent with the functional group it detects.

  2. A. Sodium bicarbonate solution

    • Carboxylic acids react with NaHCO3NaHCO_3NaHCO3​ to release CO2CO_2CO2​ gas.
    • Reaction: RCOOH+NaHCO3→RCOONa+CO2+H2ORCOOH + NaHCO_3 \rightarrow RCOONa + CO_2 + H_2ORCOOH+NaHCO3​→RCOONa+CO2​+H2​O
    • So, A →\to→ II (carboxylic acid).

  3. B. Neutral ferric chloride

    • Neutral FeCl3FeCl_3FeCl3​ gives a colored complex with phenols.
    • Hence, B →\to→ III (phenolic −OH-OH−OH).

  4. C. Ceric ammonium nitrate

    • Ceric ammonium nitrate test is used for alcohols.
    • Alcohols give a red/orange coloration.
    • Therefore, C →\to→ IV (alcoholic −OH-OH−OH).

  5. D. Alkaline KMnO4KMnO_4KMnO4​

    • Alkaline potassium permanganate is Baeyer's reagent, used to detect unsaturation such as C=CC=CC=C double bond.
    • Thus, D →\to→ I (double bond/unsaturation).

  6. Final matching: A−II,  B−III,  C−IV,  D−IA-II, \; B-III, \; C-IV, \; D-IA−II,B−III,C−IV,D−I

  7. Compare with options:

    • Option D: A−II,B−III,C−IV,D−IA-II, B-III, C-IV, D-IA−II,B−III,C−IV,D−I

So, the correct option is D.
