Question

1.The Ar2+ ion has been observed in the gas phase. Draw a molecular orbital diagram for Ar2+. Just think about what would happen with the 3p orbitals; ignore contributions of the 3s or any other lower atomic orbitals. Calculate bond order and describe how the bond distance in this ion would differ from that in Cl2.

2. Draw a molecular orbital diagram of B2 that shows why B2 is paramagnetic. Explain, in your own words, (a) what “mixing” has to do with this diagram, (b) why mixing occurs for this molecule, and (c) why B2 would be diamagnetic in the absence of mixing.
