So in biochemistry, if somebody ever tells you or refers to the Vanderbilts forces, they are probably referring to the London dispersion forces. The reason this is technically incorrect is because actually, all intermolecular bonds are technically vanderball's forces. But sometimes in biochemistry, they use these two terms interchangeably. So, what exactly is a London dispersion force? Well, it's an electric force that exists between two groups of atoms that have instantaneous dipole moments. So, what exactly do we mean by that?
