The species having bond order different from that in $\mathrm{CO}$ is

A

$\mathrm{NO}^{-}$

B

$\mathrm{NO}^{+}$

C

$\mathrm{CN}^{-}$

D

$\mathrm{N}_2$

(IIT-2007)

Solution

$\mathrm{NO}^{-}$($16$ electron system)

Bond order $=2$.

$\mathrm{NO}^{\oplus}, \mathrm{CN}^{-}$and $\mathrm{N}_2$ are isoelectronic with $\mathrm{CO}$ therefore all have same bond order $(=3)$

Hence ($A$) is correct.
