If the bond order of $\mathrm{CO}$ is $\mathrm{x}$, the bond order of $\mathrm{O}_2^{2-}$ ion is
If the bond order of $\mathrm{CO}$ is $\mathrm{x}$, the bond order of $\mathrm{O}_2^{2-}$ ion is
$\mathrm{X}$
$\mathrm{x} / 2$
$x / 3$
$2 \mathrm{x}$
Solution
Bond order of $\mathrm{O}_2^{2-}=\frac{1}{2}(10-8)=1$
Bond order of $\mathrm{CO}=3=\mathrm{x}$
$\therefore \quad$ Bond order of $\mathrm{O}_2^{2-}=\frac{\mathrm{x}}{3}$
