Explanation

The entropy of a substance is related to the number of ways its particles can be arranged. In the case of hydrogen halides, the entropy generally increases with increasing molecular weight. Therefore, among the options provided, hydrogen iodide (HI) would have the highest entropy value due to its larger molecular weight compared to HF, HCl, and HBr.
