What is the stock notation of Manganese dioxide?
- A \(\mathrm{Mn}(\mathrm{I}) \mathrm{O}_2\)
- B \(\mathrm{Mn}(\mathrm{II}) \mathrm{O}_2\)
- C \(\mathrm{Mn}(\mathrm{III}) \mathrm{O}_2\)
- D \(\mathrm{Mn}(\mathrm{IV}) \mathrm{O}_2\)
Answer & Solution
Correct Answer
(D) \(\mathrm{Mn}(\mathrm{IV}) \mathrm{O}_2\)
Step-by-step Solution
Detailed explanation
The oxidation state of \(\mathrm{Mn}\) in manganese dioxde \(\left(\mathrm{MnO}_2\right)\) is +4 . Hence, the stock notation is \(\mathrm{Mn}(\mathrm{IV}) \mathrm{O}_2\).
