The weakest (in strength) of the following intermolecular forces is_______________?
Correct answer: B. Vander Waals force
- A. Hydrogen bonding
- B. Vander Waals force
- C. Forces among the polar molecules
- D. Ionic bond
Explanation
Van der Waals forces, especially London dispersion forces, are the weakest listed intermolecular attractions. Hydrogen bonding and dipole-dipole attractions between polar molecules are stronger, while an ionic bond is much stronger and is not usually classified as an intermolecular force. Students may choose c by treating all polar-molecule attractions as weaker than dispersion forces.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
