Question

What is the interaction energy associated with the London force?

Answer 1

London forces:

• “ The force of attraction between two temporary dipoles is known as London forces. Another name for this force is dispersion force.”
• It is the weakest type of intermolecular force.

Interaction energy associated with the London force:

• The interaction energy is associated with the interaction caused between particles.
• The interaction energy has an inverse relation with the distance between two particles.
• It can be expressed as:

$\mathrm{Interaction}\mathrm{energy}\propto \frac{1}{{\mathrm{r}}^6}$, where $\mathrm{r}$ is the distance between two interacting particles.
