Q. According to bond order concept the correct order of stability of $O_{2}$, $O_{2}^{+}$, and $O_{2}^{-}$ is
A) $O_{2} > O_{2}^{+} > O_{2}^{-}$
B) $O_{2}^{-} > O_{2} > O_{2}^{+}$
C) $O_{2} > O_{2}^{-} > O_{2}^{+}$
D) $O_{2}^{+} > O_{2} > O_{2}^{-}$
Explanation
(d)
Bond order $\propto$ stability
Species Bond order
$O_{2}^{+}$ 2.5
$O_{2}$ 2.0
$O_{2}^{-}$ 1.5
Hence, the order of stability is
$O_{2}^{+} > O_{2} > O_{2}^{-}$
