(a) How does bond energy vary from `N_(2)^(+)` and `N_(2)^(-)` and why ?
(b) On the basis of the molecular orbital theory, what is the similarly between :
`(i)F_(2),O_(2)^(2-)" "(ii)CO,N_(2),NO^(+).`
(c ) Like CO why its analong SiO is not so stable ?

Explanation

Bond energy of `N _(2) ^(+)=` Bond energy of `N _(2) ^(-) ` because bond order is same in both the species. [However,`N_(2) ^(+)` is slightly more stable than `N _(2) ^(-)` as antibonding electrons number is higher in `N _(2) ^(-)` than in `N _(2)^(+).`]
