Q49 / 180 · NEET 2017 · Chemistry

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

A
$CO, NO$
B
$O_{2}, {NO}^{+}$
Correct answer
C
${CN}^{-}, CO$
D
$N_{2}, O_{2}^{-}$

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.

Hence, the correct answer is option: 'C'.
