Vedclass · Answer

(C) If $2s-2p$ mixing is not operative,the energy order of molecular orbitals is: $\sigma 1s Electronic configurations: $Be_2$ ($8$ electrons): $(\sigma 1s)^2, (\sigma^* 1s)^2, (\sigma 2s)^2, (\sigma^* 2s)^2$ (Diamagnetic). $B_2$ ($10$ electrons): $(\sigma 1s)^2, (\sigma^* 1s)^2, (\sigma 2s)^2, (\sigma^* 2s)^2, (\sigma 2p_z)^2$ (Diamagnetic). $C_2$ ($12$ electrons): $(\sigma 1s)^2, (\sigma^* 1s)^2, (\sigma 2s)^2, (\sigma^* 2s)^2, (\sigma 2p_z)^2, (\pi 2p_x)^1, (\pi 2p_y)^1$ (Paramagnetic due to two unpaired electrons). $N_2$ ($14$ electrons): $(\sigma 1s)^2, (\sigma^* 1s)^2, (\sigma 2s)^2, (\sigma^* 2s)^2, (\sigma 2p_z)^2, (\pi 2p_x)^2, (\pi 2p_y)^2$ (Diamagnetic).

Assuming $2s-2p$ mixing is $NOT$ operative,the paramagnetic species among the following is:
