Per NCERT §4.8 (O₂), the MOT prediction for OXYGEN MOLECULE explains which experimental observation that earlier theories could not?
AO₂ doesn't exist
BO₂ is diamagnetic
CO₂ has bond order 3
DO₂ is PARAMAGNETIC — MOT places 2 unpaired e⁻ in degenerate π*2p_x and π*2p_y MOs
Answer & Solution
Correct answer: D. O₂ is PARAMAGNETIC — MOT places 2 unpaired e⁻ in degenerate π*2p_x and π*2p_y MOs
Per NCERT §4.8(5), O₂ MO config has two unpaired e⁻ in π* MOs → paramagnetic. Bond order 2. Lewis structure could not explain paramagnetism.
