Solution

$\begin{matrix} Species & Bond order & Number of unpaired electron N_{2} & 3 & 0 N_{2}^{+} & 2.5 & 1 N O^{+} & 3 & 0 N O^{-} & 2 & 2 C O & 3 & 0 C N^{-} & 3 & 0 O_{2}^{-} & 1.5 & 1 O_{2}^{- 2} & 1 & 0 \end{matrix}$
Bond order of $N_{2}, N O^{+}, C O, C N^{-}$ is greater than 2.5 and they are dimagnetic species.
