Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The maximum oxidation state of a transition element often corresponds to the total number of valence electrons (s and d).
- Sc (3d\(^1\) 4s\(^2\)): +3
- Fe (3d\(^6\) 4s\(^2\)): +6 (in ferrates)
- Mn (3d\(^5\) 4s\(^2\)): +7 (in permanganates, e.g., KMnO\(_4\))
- V (3d\(^3\) 4s\(^2\)): +5
Mn shows the highest oxidation state.
Answer: Mn.
- Sc (3d\(^1\) 4s\(^2\)): +3
- Fe (3d\(^6\) 4s\(^2\)): +6 (in ferrates)
- Mn (3d\(^5\) 4s\(^2\)): +7 (in permanganates, e.g., KMnO\(_4\))
- V (3d\(^3\) 4s\(^2\)): +5
Mn shows the highest oxidation state.
Answer: Mn.
