Vedclass · Answer

(A) The bond order of a diatomic species depends on the total number of electrons in the molecule or ion.Species with the same number of electrons are isoelectronic and generally possess the same bond order.Calculating the total number of electrons for each species:$CN^{-}$: $6 + 7 + 1 = 14$ electrons.$NO^{+}$: $7 + 8 - 1 = 14$ electrons.$CN^{+}$: $6 + 7 - 1 = 12$ electrons.$O_2^{-}$: $8 + 8 + 1 = 17$ electrons.Since $CN^{-}$ and $NO^{+}$ both have $14$ electrons,they have the same bond order (which is $3$).

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