Solution
Correct Answer:
NaCl precipitates out in acetone
The reaction proceeds by nucleophilic substitution where I- replaces Cl-. In acetone, NaI is soluble but NaCl is not, so NaCl precipitates and removes product-side salt from solution. This drives equilibrium forward by Le Chatelier's principle, making the conversion efficient.
This medium difficulty chemistry question is from the chapter organic compounds containing halogens, covering the topic of finkelstein reaction. It appeared in the 2025 exam.
