Answer:
The compound that will be most soluble in water is a polar compound with hydrogen bonding capabilities.
Step-by-step explanation:
Polar compounds have an uneven distribution of electron density, resulting in partial positive and partial negative charges. Water is a polar solvent, and it can effectively interact with and dissolve other polar compounds through hydrogen bonding. Therefore, a compound that is highly polar and capable of forming strong hydrogen bonds with water molecules will be the most soluble in water.
