Question

The purple colour of KMnO\(_4\) is due to:

• A. Charge transfer
• B. d-d transition
• C. f-f transition
• D. d-f transition

Hint:

In many transition metal compounds, the color is due to charge transfer between metal ions and ligands.

Answer 1

The Correct Option is A

Step 1: Explanation of color. The purple color of KMnO\(_4\) is due to charge transfer between the manganese ion and the oxygen ligands, specifically from the oxygen to the manganese.
Step 2: Conclusion. Thus, the purple color is due to charge transfer.
