FREE Expert Solution

We’re being asked to explain the longer bond length of peroxide ion, O22-, compared to the superoxide ion, O2-


The bond energy determines the strength of the bond in a compound.

▪ the higher the bond energy, the higher is the energy required to break up the molecule/compound into its individual atoms
higher bond energy higher bond strength


The bond strength also determines the distance between the atoms
