Strong dipole-dipole forces among the liquid molecules are responsible for:
Correct answer: A. Very high heat of vaporization
- A. Very high heat of vaporization
- B. Very low boiling point
- C. Very low heat of vaporization
- D. All are correct
Explanation
Strong dipole-dipole forces among liquid molecules require a significant amount of energy to overcome when transitioning from the liquid to the vapor phase. As a result, substances with strong dipole-dipole forces tend to have a high heat of vaporization.

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.
