Question

Which pair of species given below have same bond order. (a) O2+, N2-, (b) O2+, O2- (c) F2+, N2- (d) F2+, O2-​

Answer 1

Answer:

a and d pair of species have the same bond order

Answer 2

$O^{2+}, N^{2-}$ and $F^{2+}, O^{2-}$ these species have the same bond order.

1. Bond order = [(Bonding molecules' number of electrons) – (Antibonding molecules' number of electrons)]/2
2. The bond order of $O^{2+}, N^{2-}$ is 2.5.
3. And the bond order in $F^{2+}, O^{2-}$ is 1.5
