What is the stock notation of Manganese dioxide?

Options

  1. AMn ( I ) O ₂
  2. BMn ( II ) O ₂
  3. CMn ( III ) O ₂
  4. DMn ( IV ) O ₂

Correct answer

D. Mn ( IV ) O ₂

Step-by-step solution

The oxidation state of Mn in manganese dioxde ( MnO ₂ ) is +4 . Hence, the stock notation is Mn ( IV ) O ₂ .
