Are London dispersion forces present in every molecule?

Postby Mario Reyes 1C » Fri Jun 08, 2018 6:15 pm

Is it safe to say that London dispersion forces are present in every molecule? Are these forces within the molecule, or between neighboring molecules?

London dispersion forces exist between any two molecules provided that they are close enough together! They are a result of the electrons in one molecule attracting to the positively charged nuclei of another molecule (This means they are present in both polar and non polar molecules).

These dispersion forces are strongest between large, heavy atoms that have valence e- farther away from the nucleus!

London dispersion forces are present between any 2 molecules that are close together
