Chemistry - CHEMICAL BONDING Question with Solution | TestHub

${\mathrm{B}}_2$ : Total electrons $=10$ Configuration : $\sigma 1s^2{\sigma }^{\ast }1s^2\sigma 2s^2{\sigma }^{\ast }2s^2\pi 2p_x^1=\pi 2p_y^1$ If Hunds rule is violated, then $$\sigma 1s^2{\sigma }^{\ast }1s^2\sigma 2s^2{\sigma }^{\ast }2s^2\pi 2p_x^2=\pi 2p_y^0$$ So, diamagnetic $$\text{ Bond order }=\frac{6-4}{2}=1$$ Chemical bonding Conceptual II
