We’re being asked to determine the compound that is most soluble in water.

Recall that the main idea in dissolution is like dissolves like, which means compounds with the same polarity and intermolecular force can dissolve each other.

Water is a polar molecule that exhibits hydrogen bonding, so the best solute is another polar compound. For this problem, we need to determine the polarity of each molecule.
