A hydrogen bond is a dipole-dipole force and is an attraction between a slightly positive hydrogen on one molecule and a slightly negative atom on another molecule. Hydrogen bonds are important in the properties of water and in certain biological molecules, such as proteins.
Similarly, the melting points of solids increase with an increase in the strengths of the intermolecular forces. Three types of intermolecular attractive forces are known to exist between neutral molecules: dipole-dipole forces, London dispersion forces, and hydrogen-bonding forces. These forces are also called van der Waals forces after Johannes van der Waals, who developed the equation for predicting the deviation of gases from ideal behavior.
