Q. Using MO theory predict which of the following species has the shortest bond length?

A) $O_{2}^{2 +}$
B) $O_{2}^{+}$
C) $O_{2}^{-}$
D) $O_{2}^{2 -}$
Explanation

(a)
Higher the bond order short the bond length $O_{2}^{2 +}$ has the shortest the bond length (BO=3)
Bond order of remaining species are :
$O_{2}^{+}(2.5),\ \ O_{2}^{-}(1.5)\$and$\ O_{2}^{2 -}(1)$
