Why do temporary dipole forces cause attraction when there should be the same amount of repulsive forces as attractive.

>> No.8131121

The opposite charge is slightly closer, so the attraction is slightly greater.

no b/c distance matters

>> No.8131126

>>8131119
attractive forces decrease the distance, causing the force to increase in strength vs the opposing forces which weaken because the distance here is increased.

in addition to this, as the force increases, the potential energy is reduced and this leads as well to a thermodynamic stability which favors these types of interactions

good explanation, always wondered about LDF

but on average, shouldn't the net force from all the molecules on one molecule at any one time be approximately zero? How does this cause a net attraction?
