Which of the following is a false statement about dispersion forces? view available hint(s) which of the following is a false statement about dispersion forces? dispersion forces are the result of fluctuations in the electron distribution within molecules or atoms. dispersion forces are present in all atoms and molecules. dispersion forces result from the formation of instantaneous dipoles in a molecule or atom. dispersion forces always have a greater magnitude in molecules with a greater molar mass. dispersion force magnitude depends on the amount of surface area available for interactions.
