$O_2$

Vedclass · Answer

(C) According to Molecular Orbital Theory $(MOT)$, the electronic configuration of $O_2$ ($16$ electrons) is: $\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2 = \pi 2p_y^2, \pi^* 2p_x^1 = \pi^* 2p_y^1$.Since $O_2$ has two unpaired electrons in its antibonding $\pi^*$ orbitals, it is paramagnetic.$Li_2$, $N_2$, and $F_2$ have all paired electrons and are diamagnetic.
