The Following Atoms Participate In Hydrogen Bonding Except

WebThere are three main types of van der Waals forces, two of which I have discussed at length on the previous page. These are dipole-dipole interactions (also known as Keesom forces) and dispersion forces (also known as London forces). The third kind of interactions (known as Debye forces) are normally overlooked at this level as being relatively ... WebWe know that even though the molar mass here is the same, the length of the chain is actually related to the London dispersion forces. So as the length of the chain goes up, that actually means that the London dispersion forces, so the intermolecular forces that happen when you get these tiny instantaneous dipoles, those forces also go up.
