Another example: an O – H bond of a Water molecule ( H – O – H ) has 493.4 kJ mol-1 of bond dissociation energy, and 424.4 kJ mol-1 is needed to cleave the remaining O – H bond. The bond energy of the O – H bonds in Water is 458.9 kJ mol-1, which is the average of the values. Some bond energy trends (units are in Kcal/mol and ( KJ / Mol )) : BOND ENERGY/DISTANCE CORRELATION Bond strength (energy) can be directly related to the Bond Distance . Therefore we can use the metallic, ionic, or covalent radii of each atom in the molecule to determine the bond strength. For example, the ''covalent'' radius of Boron is estimated at 83.0 Pm , but the bond length of B–B in B2Cl4 is 175 pm, a significantly larger value. This would indicate that the bond between the two boron atoms is a rather ''weak'' single bond. In another example, the metallic radius of Rhenium is 137.5 pm, with a Re–Re bond length of 224 pm in the compound Re2Cl8. From this data, we can conclude that the bond is a very strong bond or a Quadruple Bond . This method of determination is most useful for covalently bonded compounds .
