[[Category:Physics]]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]].

Van der Waals' forces tend to become more dominant in hydrocarbons with a polar functional group and a significantly larger hydrotrophic, insoluble region (c.f. methyl ethanoate and ethyl methanoate).
