We’re being asked to determine the best solvent for each given solute. 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, while carbon tetrachloride is a nonpolar molecule that exhibits dispersion forces. 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.
