Quizplus · Accepted Answer

2,3-dihydroxybutanal has two hydroxyl groups which can participate in hydrogen bonding with water molecules, making it the most soluble in water. 1-hydroxy-2-butanone has only one hydroxyl group, while 2-butanone and butanal do not have any functional groups that can hydrogen bond with water molecules.
