Bond order is a concept in the molecular orbital theory. It depends on the number of electrons in the bonding and antibonding orbitals. Which of the following statements is true about it? The bond order

The correct order of bond orders of $C_{2}^{2-}$,$N_{2}^{2-}$,and $O_{2}^{2-}$ is,respectively.

Which of the following statements is correct for the peroxide ion $(O_2^{2-})$?
$A.$ It has completely filled $\pi^*$ antibonding molecular orbitals.
$B.$ It is diamagnetic.
$C.$ It has a bond order of one.
$D.$ It is isoelectronic with Neon.

When $O_{2}$ is converted into $O_{2}^{+}$,what happens to its paramagnetic character and bond order?
