We’re being asked to determine which gas is least 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 (H2O) is a polar molecule that exhibits hydrogen bonding, so the least soluble gas would be a nonpolar compound.
Which of these compounds would you expect to be least soluble in water?
