Question

In the compounds $KMn{O}_4$ and $K_{2}C{r}_2{O}_7$, the highest oxidation state is of the element.

• A. Potassium
• B. Chromium
• C. Oxygen
• D. Manganese

Answer 1

The correct option is D Manganese

In $KMn{O}_4$ , $K$ is in +1 oxidation state, $O$ is in -2 oxidation state $Mn$ is present in +7 oxidation state.

In $K_2{Cr}_2{O}_7$,$K$ is in +1 oxidation state, $O$ is in -2 oxidation state $Cr$ is present in +6 oxidation state.

So $Mn$ is present in highest oxidation state.
