Assuming

2 s-2 p

mixing is NOT operative, the paramagnetic species among the following is

View answer and explanation

Correct option: B

{B}_2

Option B (

{B}_2

) is correct. Without 2s-2p mixing, the electronic configuration of

{B}_2

results in two unpaired electrons in the

\pi_{2p}

orbitals, making it paramagnetic.
