$NO^{-}$

Vedclass · Answer

(A) To determine the magnetic nature,we calculate the total number of electrons and use Molecular Orbital Theory $(MOT)$.$NO^{-}$ has $16$ electrons. The electronic configuration is $\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2 = \pi 2p_y^2, \pi^* 2p_x^1 = \pi^* 2p_y^1$.Since it contains two unpaired electrons in the $\pi^*$ orbitals,it is paramagnetic.$O_2^{2-}$ has $18$ electrons and is diamagnetic.$CN^{-}$ has $14$ electrons and is diamagnetic.$CO$ has $14$ electrons and is diamagnetic.
