MCQ
$O - O$ bond length order in $O _2^{-2}, O _2^{-}, O _3$ and $O _2$ :
- A$O _2^{-2}< O _2^{-}< O _3< O _2$
- B$O _2^{-2}> O _2^{-}> O _3> O _2$
- ✓$O _2^{-2}> O _2^{-}= O _3> O _2$
- D$O _2^{-2}< O _2^{-}= O _3< O _2$
✓
Answer
Correct option: C.
$O _2^{-2}> O _2^{-}= O _3> O _2$
(C) $O _2^{-2}> O _2^{-}= O _3> O _2$
Bond order $\propto\frac{1}{\text{ Bond lenght}} $
$\begin{array}{l} B . O = O _2^{-2}> O _2^{-}= O _3> O _2 \\ ( O - O )\end{array}$
Bond order $\propto\frac{1}{\text{ Bond lenght}} $
$\begin{array}{l} B . O = O _2^{-2}> O _2^{-}= O _3> O _2 \\ ( O - O )\end{array}$
