We’re being asked to identify the intermolecular forces present in the homogenous solution consisting of KCl and H2O

Recall: Homogenous solutions have a uniform composition. It is composed of a solute that is completely soluble in a solvent.

This follows the rule "like dissolves like" where the solute and the solvent either have the same polarity or intermolecular force.

There are several types of intermolecular forces:

1. Ion-dipole interaction – occurs between an ion and a polar covalent compound

2. Hydrogen bonding – occurs in compounds where hydrogen is directly connected to an electronegative element such as N, O, or F

3. Dipole-dipole interaction – occurs between two polar covalent compounds

4. Induced-dipole interaction – occurs when a nonpolar compound interacts with a polar compound

5. Dispersion forces – occurs in all compounds. This is the primary intermolecular force exhibited by nonpolar compounds.

For this problem, we need to do the following steps to each compound:

Step 1: Determine the central atom in the molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.

Step 4: Determine the polarity and IMF of the molecule.

Then, determine the intermolecular force between the two compounds.
