question 77

Multiple Choice

The order of MO energies in B₂, C₂, and N₂ (σ_2p > π_2p) , is different from the order in O₂, F₂, and Ne₂ (σ_2p > π_2p) . This is due to ________.

• A)less effective overlap of p orbitals in O₂, F₂, and Ne₂
• B)the more metallic character of boron, carbon and nitrogen as compared to oxygen, fluorine, and neon
• C)greater 2s-2p interaction in O₂, F₂, and Ne₂
• D)greater 2s-2p interaction in B₂, C₂, and N₂
• E)less effective overlap of p orbitals in B₂, C₂, and N₂
