(a) How bond energy veries from ` N_(2) ^(-) ` to ` N_(2)^(+)` and why ?
(b) On the basis of molecular orbital theory what is similartiy between
(i) ` F_(2), O_(2) ^(- )` (ii) ` CO, N_(2) , NO^(+)` ?

Explanation

(a) Bond energy of ` N_(2)^(+)` = Bond energy of ` N_(2)^(-)` . This is because they have the same bond order.
(Strictly speaking , ` N_(2)^(-)` is slightly less stable and hence has less bond energy then `1 N_(2)^(+)` due to presnece of
greater number of electrons in the antibonding molecular orbitals )
(b) (i) Same bond order and bond lenght . (ii) Same bond order and bond length .
