Question

On the basis of molecular orbital theory what are the similarities between —

(a) $F_2, O_2^{2-}$

(b) CO, N₂, NO⁺ 

Answer 1

(a) ${F}_2$ and ${O}_2^{2-}$ have same bond order of 1 due to same molecular orbital electronic configuration. Hence, these are assumed to have same bond energy and bond length.

(b) Similarly ${CO}, {N}_2$ and ${NO}^{+}$have same molecular orbital electronic configuration thus, they have same bond order and bond length.
