In Wednesday's lecture, Dr. Lavelle said that London interactions are always present and attractive. What did he mean by present? Like are London dispersion forces also present in compounds with ionic or hydrogen bonds?
I believe that London dispersion forces generally act as intermolecular forces between any molecules that are close to each other, regardless of type. All molecules have electrons which may be pulled/distorted slightly by London dispersion forces. For any intermolecular interaction I believe, LDF will always be happening in the background. Non-polar molecules, however, will only exhibit London dispersion forces.
Technically, London Dispersion forces are always present. It is a matter of what forces are dominating in those interactions. Such as London Dispersion forces being present in ionic bonds but the ionic forces are more dominant.
