Recall that 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.
