Van Der Waals Interaction
Do all molecules have Van Der Waals interactions? What is the order of strongest to weakest interactions ?

Re: Van Der Waals Interaction
Yes, all molecules and atoms have Van der Waals interactions (can also be referred to as instantaneous dipoles or london dispersion forces). The strongest forces to weakest forces are ion-dipole, hydrogen bonds, dipole-dipole, and then van der waals/instantaneous dipoles/LDF.
Re: Van Der Waals Interaction
Yes, all molecules regardless of their polarity or non-polarity experience Van Der Waals interactions due to shift in the electron cloud density. The order of interaction from strongest to weakest is ion-dipole, dipole-dipole, dipole-induced dipole, induced dipole-induced dipole.

Re: Van Der Waals Interaction
Yes all molecules experience Van der Waals forces and it has the lowest interaction, although it has the potential to have the strongest interactions

Re: Van Der Waals Interaction
In terms of molecules containing only Van Der Waals interactions: the larger the size of the molecule, the more interactions there are, meaning that the interactions in that given molecule are stronger relative to one with a smaller size/less interactions.

Re: Van Der Waals Interaction
Since every molecule has electrons, every molecule will experience these forces. A van der waal force or induced dipole - induced dipole will be created because some discrepancy in electron density will create induced dipoles.

Re: Van Der Waals Interaction
Yes, every molecule experiences these forces, the strongest to weakest would be as follows: ion-dipole, hydrogen bonds, dipole-dipole, and lastly, Van Der Waals.

Re: Van Der Waals Interaction
^^^ what they said, van der waals forces are constant but also constantly changing, that is why it is useful to think of them as induced-diple induced-dipole forces
Re: Van Der Waals Interaction
any atom that interacts with another atom will have these forces because it has electrons that are available for induced dipole movement. that being said, larger atoms have stronger van der waals forces because they have more electrons.
