Part IV: Bond Energy and Bond Length The strength of a covalent bond is measured by the bond energy. There are tables of average bond energies in your textbook. It is important to remember that these values represent average bond energies. For example, a table may give a value of 745 kJ/mol for C-O, but the actual value in Co, is 799 kJ/mol. Therefore any calculations using these values will only be approximate, The length of a covalent bond is...
