Question

The colour of $KMn{O}_4$ is due to:

• A. M $\to$ L charge transfer transition
• B. d-d transition
• C. L $\to$ M charge transfer transition
• D. $\sigma -{\sigma }^{\ast }$ transition

Answer 1

The correct option is C L $\to$ M charge transfer transition

The colour arises due to charge transfer from the ligand to the central metal atom.
