Which of the following statements about liquids is true?
A)Droplet formation occurs because of the higher stability associated with increased surface area.
B)Substances that can form hydrogen bonds will display lower melting points than predicted from periodic trends.
C)London dispersion forces arise from a distortion of the electron clouds within a molecule or atom.
D)Liquid rise within a capillary tube because of the small size lowers the effective atmospheric pressure over the surface of the liquid.
E)The boiling point of a solution is dependent solely on the atmospheric pressure over the solution.

Question

Quizplus · Accepted Answer

London dispersion forces, a type of van der Waals force, indeed result from temporary fluctuations in electron density that lead to temporary dipole moments, causing attraction between atoms or molecules. This is a fundamental interaction for all atoms and molecules, including those in the liquid state.
