IB Chemistry - Intermolecular Bonding Essay:

lain the following:There exists four types of intermolecular bonding, they include ionic, covalent, Van der waals and hydrogen bonding. In order to describe the existence of such bonding you must also ... molecules to come together. This is the basis for another branch of intermolecular forces known as Van der waals forces. These forces are weak, short-ranged forces of attraction between molecules. Th ...
