The lowest energy excited state corresponds to an electron being excited from π to σ, leading to the configuration σ2 σ*2 π3 σ1. Consistent with Hund's rule, one orbital is doubly occupied and the other two singly occupied, so the oxygen atom is paramagnetic (2 unpaired electrons.) Oxygen is paramagnetic means , it is attracted by the magnetic field but does not remain magnetic once it leaves the field. c. is diamagnetic. orbital? For diamagnetic character, there should not be any unpaired electron in the molecules formation. These properties can be explained by the molecular orbital diagram of BN".
