We’re being asked to identify the intermolecular forces present in the homogenous solution consisting of LiNO3 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 will do the following steps:
Step 1: determine the polarity and IMF of the molecule.
Step 2: determine the intermolecular force between the two compounds.
Indicate the types of forces that are involved when forming a homogeneous solution between LiNO3 and H2O.
