• # question_answer 40) Compare the relative stabilities of the following species and indicate their magnetic properties ${{O}_{2}},O_{2}^{+},O_{2}^{-}$ and $O_{2}^{2-}$

For bond orders of ${{O}_{2}},O_{2}^{+}$ and $O_{2}^{-}$ refer to Q. 4.40 $O_{2}^{2-}:KK\sigma {{(2s)}^{2}}\overset{*}{\mathop{\sigma }}\,{{(2s)}^{2}}\sigma {{(2{{p}_{z}})}^{2}}\pi {{(2{{p}_{x}})}^{2}}\pi {{(2{{p}_{y}})}^{2}}$ $\overset{*}{\mathop{\pi }}\,{{(2{{p}_{x}})}^{2}}\pi {{(2{{p}_{y}})}^{2}}$ Bond order = $\frac{8-6}{2}=1$ Stability order \[\underset{Diamagnetic}{\mathop{O_{2}^{2-}}}\,
