💡 Solution & Explanation

Step 1 - Identify the reaction in Statement-1: The reaction shown is CH3-CH2-Cl reacting with NaI in acetone to give CH3-CH2-I and NaCl precipitate. This is the classic Finkelstein reaction, an SN2 halide exchange reaction where NaI in acetone converts alkyl chlorides (or bromides) into alkyl iodides. Statement-1 is TRUE. Step 2 - Evaluate Statement-2: Statement-2 claims that acetone is a 'polar-protic' solvent. This is INCORRECT. Acetone (propanone) is a polar APROTIC solvent. It is polar due to its carbonyl group dipole, but it lacks an O-H or N-H bond, so it cannot donate hydrogen bonds and is therefore aprotic, not protic. Examples of polar protic solvents are water, alcohols, and acetic acid. This factual error makes Statement-2 FALSE. Step 3 - Evaluate the rest of Statement-2: While the solubility order NaI > NaBr > NaCl in acetone is correct, and the driving force by precipitation of NaCl is correct, the initial classification of acetone as polar-protic is a clear chemical error that renders Statement-2 false overall. Step 4 - Match to options: - Option (a): Both true, S2 explains S1 — incorrect because S2 is false. - Option (b): Both true, S2 does not explain S1 — incorrect because S2 is false. - Option (c): S1 is true, S2 is false — correct. - Option (d): S1 is false, S2 is true — incorrect because S1 is true and S2 is false. Therefore, the correct answer is {"answer": ["C"], "note": "The reaction is Finkelstein reaction."}.
