London dispersion forces are a function of the molar mass of substances. What happens to the dispersion forces of the molecules as the molar mass increases?
A. They are increased.
B. They are decreased.
C. They remain the same.
D. They cannot be measured.
London dispersion forces are a function of the molar mass of substances. What happens to the dispersion forces of the molecules as the molar mass increases?
Generally, London dispersion forces depend on the atomic or molecular weight of the material. Heavier atoms or molecules have more electrons, and stronger London forces. This means that they are harder to melt or boil.
