The correct energy ordering of molecular orbitals for O₂ and F₂ is:
- A σ_2p < π_2p < π*_2p < σ*_2p
- B π_2p < σ_2p < π*_2p < σ*_2p
- C σ_2p < σ*_2p < π_2p < π*_2p
- D π*_2p < σ*_2p < π_2p < σ_2p
Explanation
For O₂ and F₂, the σ_2p orbital is lower than the π_2p orbitals. For N₂ and lighter diatomics, the ordering is reversed.
