London forces and dipole moments
When instantaneous dipole dipole moments are produced at a greater rate, can we correctly say that the London forces increase in strength?

Re: London forces and dipole moments
I'm not sure what you mean by greater rate of dipole dipole moment, but from what I understand, London forces increase when size or mass of atoms increase.

Re: London forces and dipole moments
Temporary dipole dipole moments happen more frequently when the size of the molecule increases. If a given amount of substance experiences more of these dipole dipole moments that would mean that the london forces are stronger in that molecule.

Re: London forces and dipole moments
London forces are the weakest of all intermolecular forces, and they increase in strength as the total number of electrons increase.

Re: London forces and dipole moments
Bigger molecules and more polarizable molecules both have stronger of London forces. A bigger molecule has more electrons and therefore a higher chance of causing an instantaneous dipole moment (like you asked), so with more of these moments, the force exuded will be stronger.
