Match List-I with List-II

Choose the correct answer from the options given below:

(A)-(III), (B)-(IV), (C)-(I), (D)-(II)

The correct answer is Option (3) → (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

(A) Acetone to secondary alcohol Acetone (CH₃COCH₃) is a ketone. Ketones are reduced to secondary alcohols using NaBH₄ (sodium borohydride) or LiAlH₄. → (III) NaBH₄

(B) Ethanol to Diethyl ether Ethanol → Diethyl ether is done by dehydration using conc. H₂SO₄ at 413 K (140°C). At this temperature, intermolecular dehydration occurs forming ether. → (IV) H₂SO₄ at 413 K

(C) Ethanol to ethanol This means no change (or purification). The reagent that does not react with ethanol under normal conditions from the list is CrO₃ (Chromic anhydride). CrO₃ oxidizes only aldehydes or primary alcohols to acids under strong conditions, but it does not oxidize ethanol easily in the context of this list (or sometimes used in distillation to keep ethanol unchanged while oxidizing impurities like aldehydes). Among the given options, CrO₃ (I) is the one that does not convert ethanol to something else. → (I) CrO₃

(D) Phenol to Benzene Phenol is converted to benzene by distillation with zinc dust (Zn). C₆H₅OH + Zn → C₆H₆ + ZnO → (II) Zn
