Hydrogen bonds are especially strong intermolecular forces. They exist when you have a negative O, N, or F atom in one molecule and a positive H atom attached to an O, N, or F atom in another molecule. Water is the best-known compound that has hydrogen bonds. Hydrogen bonds have strengths ranging from 5 kJ/mol to 50 kJ/mol.
