Bond order of $1.5$ is shown by-
$O_{2}^+$
$O_{2}^-$
$O_2^{2-}$
$O_2$
The number of antibonding electron pairs in $O_2^{2 - }$ molecular ion on the basis of molecular orbital theory is
The molecular orbital configuration of a diatomic molecule is
$\sigma \,\,1{s^2}\,\,{\sigma ^*}\,\,1{s^2}\,\sigma \,\,2{s^2}\,{\sigma ^*}\,2{s^2}\,\,\sigma \,2p_x^2\,\left\{ {{}_{\pi \,2p_z^2}^{\pi \,2p_y^2}} \right.$
Its bond order is
When two atomic orbitals combine they form
Sum of bond order of $\mathrm{CO}$ and $\mathrm{NO}^{+}$is____________.
