18.

What is the relationship between molecular size and London dispersion forces?

a)

The strength of dispersion forces decreases with molecular size and surface area.

b)

The strength of dispersion forces remains constant regardless of molecular size.

c)

The strength of dispersion forces increases with molecular size and surface area, as larger molecules have more electrons and a greater likelihood of forming temporary dipoles.

d)

The strength of dispersion forces is only dependent on the temperature of the substance.

19.

How do intermolecular forces influence boiling points?

a)

Intermolecular forces have no effect on boiling points.
