The Van der Waals 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 der Waals force. They are far weaker than intramolecular bonding such as ionic, polar or covalent bonding. Non-polar substances also have very weak Van der Waals forces, called the London dispersion force.
