Problem: Why are Van der Waals forces important?A) They determine how strong dipole moments will be in polar covalent moleculesB) They are the strongest type of intermolecular force that can act on polar and non-polar moleculesC) They are primary intermolecular attractive forces that can act between non-polar moleculesD) They are the strongest type of intermolecular force that can act between atoms

FREE Expert Solution

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/ Van der Waals forces – occurs in all compounds. This is the primary intermolecular force exhibited by nonpolar compounds.
