Per NCERT §4.8 (Li₂), the BOND ORDER and magnetic nature of Li₂ from MOT are which?
ABond order 3; ferromagnetic
BBond order 1; diamagnetic — Li₂ has been observed in vapour phase
CBond order 0; nonexistent
DBond order 2; paramagnetic
Answer & Solution
Correct answer: B. Bond order 1; diamagnetic — Li₂ has been observed in vapour phase
Per NCERT §4.8(3), Li₂: KK(σ2s)², b.o. = 1, no unpaired e⁻ → diamagnetic. Observed in Li vapour.
