Solution

The correct option is A $O_{2}^{2 -}$ < $O_{2}^{-}$ < $O_{2}$ < $O_{2}^{+}$ < $O_{2}^{2 +}$
As the bond order increases, the stability of the species increases.

Bond order of $O_{2}^{2 +}$ = 3
Bond order of $O_{2}^{+}$ = 2.5
Bond order of $O_{2}$ = 2
Bond order of $O_{2}^{-}$ = 1.5
Bond order of $O_{2}^{2 -}$ = 1

and hence, the stability order is

$O_{2}^{2 -}$ < $O_{2}^{-}$ < $O_{2}$ < $O_{2}^{+}$ < $O_{2}^{2 +}$

What is the stability order of the following species? O2+2, O+2, O2, O−2,O2−2

The correct option is A O2−2<O−2< O2< O+2<O2+2 As the bond order increases, the stability of the species increases. Bond order of O2+2= 3 Bond order of O+2= 2.5 Bond order of O2= 2 Bond order of O−2= 1.5 Bond order of O2−2= 1 and hence, the stability order is O2−2<O−2< O2< O+2<O2+2
