{{move|Van der Waal forc}}The '''Van de der Waal''' force is a [[intermolecular force]] caused by electrostatic attraction. Some [[molecules]] (polar molecules) have a more negative end and a more positive end. This means that a weak electromagnetic force is present between the positive end of one molecule and the negative end of another. This is a Van de der Waal force. They are far weaker than intramolecular bonding such as ionic, polar or covalent bonding.Non-polar substances also have very weak Van de der Waal forces, called the [[London dispersion force]].
