Assuming that Hund's rule is violated, the bond order and magnetic nature of the diatomic molecule B2 is
Solution:
B2 : Total electrons =10
Configuration : σ1s2σ∗1s2σ2s2σ∗2s2π2p1x=π2p1y
If Hunds rule is violated, then
\sigma 1 s^2 \sigma^* 1 s^2 \sigma 2 s^2 \sigma^* 2 s^2 \quad \pi 2 p_x^2=\pi 2 p_y^0
So, diamagnetic
\text { Bond order }=\frac{6-4}{2}=1
Chemical bonding
