Apply molecular orbital theory to predict which species has the strongest bond. 
a) O₂                             b) O₂^–                           c) O₂⁺                          d) All the bonds are equivalent 

(a) The nitric oxide molecule, NO, readily loses one electron to form the NO⁺ ion. Which of the following is the best explanation of why this happens: (i) Oxygen is more electronegative than nitrogen, (ii) The highest energy electron in NO lies in a π_2p* molecular orbital, or (iii) The π_2p* MO in NO is completely filled.

Apply Molecular Orbital Theory to determine the bond order of HHe⁺ ion.

Using Molecular Orbital Theory, answer the following questions dealing with carbon mononitride, CN. 

Consider the H₂⁺ ion. (c) Write the electron configuration of the ion in terms of its MOs. (d) What is the bond order in H₂⁺?
