Vedclass · Answer

(D) $KO_2$ is a superoxide compound consisting of $K^{+}$ and $O_2^{-}$ ions. The $K^{+}$ ion has a noble gas configuration and is diamagnetic. The superoxide ion $O_2^{-}$ has $17$ electrons. According to molecular orbital theory, the electronic configuration of $O_2^{-}$ is $\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2 = \pi 2p_y^2, \pi^* 2p_x^2 = \pi^* 2p_y^1$. Due to the presence of one unpaired electron in the $\pi^* 2p$ orbital, $O_2^{-}$ is paramagnetic.

$KO_2$ exhibits paramagnetic behaviour. This is due to the paramagnetic nature of
