We’re being asked to determine the compound that is most soluble in water (H2O). 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 exhibits hydrogen bonding, so the best solute is another polar compound that also exhibits hydrogen bonding. So for this, we need to draw the Lewis structures of the given choices and determine their polarity.

Step 1: Determine the central atom in this molecule.

Step 2: Calculate the total number of valence electrons present and draw the Lewis structure for the molecule.

Step 3: Determine the polarity of the molecule.
