Vedclass · Answer

(C) According to Molecular Orbital Theory $(MOT)$,a species is paramagnetic if it contains one or more unpaired electrons.$1$. $O_2^-$ has $17$ electrons. Its electronic configuration is $\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2 = \pi 2p_y^2, \pi^* 2p_x^2 = \pi^* 2p_y^1$. Since it has an unpaired electron,it is paramagnetic.$2$. $NO$ has $15$ electrons. Its electronic configuration is $\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2 = \pi 2p_y^2, \pi^* 2p_x^1$. Since it has an unpaired electron,it is paramagnetic.$3$. $CN^-$ has $14$ electrons. All electrons are paired,so it is diamagnetic.Therefore,both $(a)$ and $(b)$ are paramagnetic.
