Question

Which one of the following is an incorrect statement?

• A. O\textsubscript{3} oxidises PbS to PbSO\textsubscript{4}
• B. O\textsubscript{3} oxidises nitric oxide to nitrogen dioxide
• C. O\textsubscript{3} oxidises aqueous KI at pH = 9.2
• D. The two oxygen–oxygen bond lengths in O\textsubscript{3} are different
• E. O\textsubscript{3} is used as an oxidizing agent in the manufacture of KMnO\textsubscript{4}

Hint:

Whenever a molecule has resonance (like $O_3$, $Benzene$, or $CO_3^{2-}$), the bond lengths are always equalized. Look for resonance to debunk claims of unequal bond lengths!

Answer 1

The Correct Option is D
