Solution: Which gas is least soluble in water?a) H2b) CO2c) NH3d) SO2

Problem

Which gas is least soluble in water?

a) H2

b) CO2

c) NH3

d) SO2

Solution

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. 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.
