FREE Expert Solution

We’re being asked to determine which substance is more 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 more soluble substance would be the polar compound. 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. or CH 3CH2OH.
