Which one of the following pairs of species has the same bond order?

Which one of the following pairs of species has the same bond order?

$CO, NO$
$O_{2}, {NO}^{+}$
${CN}^{-}, CO$
$N_{2}, O_{2}^{-}$

Solution

Total number of electrons in

{CN}^{-} = 14

Total number of electrons in

CO = 14

{CN}^{-}

and

CO

both have bond order of

3

each.
