Which of the following pair have identical bond order?

$CN^-$ and $NO^+$

$CN^-$ and $O^-_2$

$CN^-$ and $CN^+$

$NO^+$ and $O^-_2$

Answer

$CN^-$ and $NO^+$

Explanation

For pairs having identical bond order, have identical number of electrons

Number of electrons for $CN ^{-}=6+7+1=14$

Number of electrons for $NO ^{+}=7+8-1=14$

Number of electrons for $O _{2}^{-}=8+8+1=17$

Hence, $CN ^{-}$ and $NO ^{+}$ have same bond order.
