examples of hydrogen bonding

When hydrogen is covalently bonded to a highly electronegative atom, such as fluorine, chlorine, oxygen, or nitrogen, the H atom has a partial positive charge, written Hδ+.
Hδ+ is physically very small, so the density of charge on it is unusually high.
Imagine another negative or electronegative atom, say on a different molecule, approaches the Hδ+; there will be mutual attraction, resulting in a particularly strong dipole-dipole attraction. This attraction is called a hydrogen bond.
In general, hydrogen bonds are weaker than ionic and covalent bonds, but are stronger than van der Waals forces.
