Question

Diagram 9-1
The molecular orbital diagram below may be used for the following problem(s). For oxygen and fluorine, the s2p orbital should be lower in energy than the p2p. However, the diagram will still yield correct bond order and magnetic behavior for these molecules.
Energy ________ s*2p

________ ________ p*2p
________ s2p
________ ________ p2p
________ s*2s
________ s2s
________ s*1s
________ s1s
Refer to Diagram 9-1. According to molecular orbital theory, which of the following species is least likely to exist (i.e., has the lowest bond order)?
A.H22-
B.F22+
C.C22-
D.O22+
E.B22-
