A curious student is observing the bond energy table shown. They notice the bond energy for 1 type of O-O bond is 499 kJ and another is 142 kJ. Why do you think these bond energies are different? (4 pts)

The bond energy between two atoms will vary depending on the type of bond being formed. In the case of O-O bonds, the bond energy can vary depending on whether the bond is a single bond or a double bond. A single bond involves the sharing of two electrons between the two oxygen atoms, resulting in a bond energy of 499 kJ. On the other hand, a double bond involves the sharing of four electrons, resulting in a stronger bond and a higher bond energy of 142 kJ. Therefore, the differences in bond energies for different O-O bonds can be attributed to the number of electron pairs being shared between the atoms, with a greater number of shared electron pairs resulting in a stronger bond and higher bond energy.
