Question

London Dispersion of attraction between molecules always decrease with

a. increasing molecular size and increasing distance between the molecules
b. increasing molecular size and decreasing distance between the molecules
c. decreasing molecular size and increasing distance between the molecules
d. decreasing molecular size and decreasing distance between the molecules

Answer 1

Therefore, as they are less tightly held and can move easily in order to form temporary dipole, the london dispersion forces between molecules always decreases when we increase the molecular size and decrease the distance between the molecules. Therefore, the correct option is option b.
