Question

Quizplus · Accepted Answer

The alcohol with more hydroxyl groups (–OH) will dissolve more easily in water due to the ability to form hydrogen bonds with water molecules. 1,3,5-pentanetriol has three hydroxyl groups, making it the most soluble in water compared to 1-pentanol and 1,5-pentanediol, which only have one and two hydroxyl groups, respectively.
