Solution: Stabilization of an emulsion of oil in water by stearate ions.Which kind of intermolecular force attracts the stearate ion to the oil drop?

Problem

A diagram shows a round oil droplet ion in water. The oil droplet is composed of a ring of stearate ions that consist of a long hydrophobic end (a hydrocarbon chain) and a hydrophilic end (COO-). The stearate ions are arranged in the oil droplet so that the COO- ends face water and the hydrophobic ends are inside the droplet, away from water. Na+ is attracted to the COO- ends of the oil droplet.
