PDF-Intermolecular Forces Intermolecular forces are generally much weaker

. These intermolecular forces are important for many additional reasons For example solubility and vapor pressure are governed by intermolecular forces The same factors that give rise to intermolecular forces eg bond polarity can also have a profound What . exactly is a bond?
