Bond energy is a quantity that offers insight into the strength of a chemical bond.
- A weak electrostatic force of attraction exists between hydrogen atoms and small, highly electronegative atoms.
- It has a lower strength than a covalent bond.
The O-H bond in water is a covalent bond with a higher bond energy than the hydrogen bond.
- The bond energy of the covalent O-H bonds in water is reported to be the average of the two values, or 458.9 kJ/mol.
