Vedclass · Answer

(A) The molecular orbital electronic configurations are as follows:$O_2^- (17 \ e^-) = \sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2, \pi 2p_y^2, \pi^* 2p_x^2, \pi^* 2p_y^1$. Number of antibonding electrons = $2+2+2+1 = 7$.$O_2 (16 \ e^-) = \sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2, \pi 2p_y^2, \pi^* 2p_x^1, \pi^* 2p_y^1$. Number of antibonding electrons = $2+2+1+1 = 6$.$O_2^{2-} (18 \ e^-) = \sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2, \pi 2p_y^2, \pi^* 2p_x^2, \pi^* 2p_y^2$. Number of antibonding electrons = $2+2+2+2 = 8$.Therefore,the number of antibonding electrons are $7, 6,$ and $8$ respectively.

In $O_2^-$,$O_2$,and $O_2^{2-}$ molecular species,the total number of antibonding electrons respectively are
