Which of the following has a bond order of 1.5? A)O₂⁺ B)N₂ C)O₂^- D)C₂ E)none of these

Question

Quizplus · Accepted Answer

The bond order is given by (# bonding electrons - # anti-bonding electrons)/2. Both options A and C have a total of 10 bonding electrons and 5 anti-bonding electrons, giving a bond order of 1.5. However, option A has a positive charge on the phosphorus atom and a negative charge on the sulfur atom, which is not stable. Option B has only one bonding orbital and one anti-bonding orbital, giving a bond order of 0.5. Option D has only two bonding orbitals and no anti-bonding orbitals, giving a bond order of 1.
