Question

The sequence that correctly describes the relative bond strength pertaining to oxygen molecule and its cation or anion is (A) O 2 2-> O 2 -> O 2> O 2 + (B) O 2> O 2+> O 2-> O 22- (C) O 2+> O 2> O 22-> O 2- (D) O 2+> O 2> O 2-> O 22-

As bond strength propto bond order.

Q. The sequence that correctly describes the relative bond strength pertaining to oxygen molecule and its cation or anion is

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

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

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

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

As bond strength $\propto$ bond order.

Q. The sequence that correctly describes the relative bond strength pertaining to oxygen molecule and its cation or anion is

O2​2−>O2​−>O2​>O2​+

O2​>O2+​>O2−​>O22−​

O2+​>O2​>O22−​>O2−​

O2+​>O22​>O22​>O22−​

As bond strength ∝ bond order.

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

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

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

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

As bond strength $\propto$ bond order.
