Van der Waals vs Dispersion Forces

[Divya Pimparkar 1E]

How are Van der Waals and dispersion forces the same?

[AustinGrove3B]

They are all interactions that give rise to attractive forces.

The names of the two are synonymous (Van der Waals= London Disperson Forces). They are both intermolecular forces found everywhere. They occur when an electron cloud of one atom is heavily dense, while the other doesn't have a lot. This creates a temporary attraction between each other that are relatively weak case by case, but it can be strong when there are a lot of Van der Waals interaction happening. Such an example where they are strong is with the gecko.

[Elizabeth Kim 4E]

They are both intermolecular forces that are relatively weak

London dispersion forces are a type of Van der Waal’s forces. These forces always operate in any substance. In general, the heavier the molecule, the stronger the Van der Waal's force of interaction.

[Cienna Henry 1J]

London dispersion forces are a type of Van der Waal’s forces. These forces always operate in any substance. In general, the heavier the molecule, the stronger the Van der Waal's force of interaction.

So the two terms aren't completely synonymous? A London dispersion force is a type of van de waal's force but not vice versa?

Correct. There are 3 types of Van der Waals forces: Dipole-dipole forces, dispersion forces, and hydrogen bonding.

Dispersion forces exist between nonpolar molecules.

[Estelle Jung]

There are two different types of Van der Waals forces, which would be London Dispersion forces and stronger dipole-dipole forces.

[Arshia Ramesh 1G]

London dispersion is one of the types of Van der waal forces.
