Question:
In which of the following compounds, oxidation number of Mn is +6?
In which of the following compounds, oxidation number of Mn is +6?
Show Hint
Oxidation number is calculated by balancing charge contributions from all atoms in a compound.
Updated On: Mar 5, 2025
- \(Mn_2O_3\)
- \(K_2MnO_4\)
- \(KMnO_4\)
- \(MnO_2\)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Calculate oxidation number:
\[
\text{Let oxidation number of Mn be } x
\]
\[
K_2MnO_4: 2(+1) + x + 4(-2) = 0
\]
\[
2 - 8 + x = 0 \Rightarrow x = +6
\]
Thus, the oxidation number of Mn in \( K_2MnO_4 \) is +6.
