Chapter 14, Problem 87CP

Given that the ionization energy of ${\text{F}}_{\text{2}}{}^{-}$ is $\text{290}\text{. kJ/mol}$ , do the following.

1. Calculate the bond energy of ${\text{F}}_{\text{2}}{}^{-}$ . You will need tolook up the bond energy of ${\text{F}}_{\text{2}}$ and ionization energyof ${\text{F}}^{-}$ .
2. Explain the difference in bond energy between ${\text{F}}_{\text{2}}{}^{-}$ and ${\text{F}}_{\text{2}}$ using $\text{MO}$ theory.
