What is the bond order for the O₂^-anion?

Question

Quizplus · Accepted Answer

The bond order for the given species can be calculated using the formula: Bond Order = (Number of bonding electrons - Number of antibonding electrons) / 2. For the given species, the superscripts indicate the number of electrons in bonding (B) and antibonding (U) molecular orbitals. Summing these up: Bonding electrons = 12, Antibonding electrons = 4. Thus, Bond Order = (12 - 4) / 2 = 4 / 2 = 2. However, since it's an anion, we add one more electron, presumably to an antibonding orbital, making the calculation: (12 - (4+1)) / 2 = (12 - 5) / 2 = 7 / 2 = 3.5 / 2 = 3/2.
