How do hydrogen bonds affect solubility?
Molecules that can hydrogen bond with water have a higher solubility in water.
Molecules which are capable of hydrogen bonds have hydrogen atoms which are covalently bonded to highly electronegative elements (O, N, F). The presence of hydrogen bonding between molecules of a substance indicates that the molecules are polar. This means the molecules will be soluble in a polar solvent such as water.
Some examples of polar molecules which can hydrogen bond are ammonia (
