hard
Which one of the following pairs of species have the same bond order ?
A
$O_2, NO^+$
B
$CN^-, CO$
C
$N_2, O_{2}^-$
D
$CO, NO$
(NEET-2017)
Solution
Total no. of electrons in $\mathrm{CN}^{-}$ is $14$
Total no. of electrons in $\mathrm{CO}$ is also $14$
hence B.O. of both $\mathrm{CN}^{-} \& \mathrm{CO}$ is $3$
