Question

Which of the following pairs of species have the same bond order?

C O, N O

O_{2}, N O^{+}

C N^{-}, C O

N_{2}, O_{2}^{-}

Solution

The correct option is C $C N^{-}, C O$

Molecule Bond order

CO 3

NO 2.5

$O_{2}$ 2

$N O^{+}$ 3

$C N^{-}$ 3

$N_{2}$ 3

$O_{2}^{-}$ 1.5

So, $C N^{-}, C O$ has same bond order.
