"WebbHowever, there is no simple relationship that allows to convert the bond length into energy or vice versa. Bond energy is a measure of its strength. The higher is the bond energy, the more work you have to do to break it. The bond energy increases with its multiplicity. " - Simple bond energy calculations

WebbThird, bond energy (in a covalent bond) is primarily determined by how well the electron orbitals overlap from the two atoms. Greater overlap creates a stronger bond. Effective nuclear charge isn't as major a factor as the overlap. We can determine things like electronegativity or bond polarity with the help of effective nuclear charge however. WebbQuantum chemical calculations using MP2/6-31+G∗ or MP2/6-31G∗ methods were performed on simple oxo acids and corresponding esters of phosphorus, for the purpose of establishing the existence of an anomeric effect (AE).
