SOLVED: [MnO4]- is deep purple in color whereas [ReO4]- is colorless. This is due to greater energy required for 1. d-d transitions in the Re compound compared to the Mn compound 2.

VIDEO ANSWER: We can say permanganate permanganate iron, which is here, or we can say intense, intense purple colorati. The oxidation state of the manganese can be found in the m n, o 4 negative. Here, we can say that it is plus 7. The electrons are
[MnO4]- is deep purple in color whereas [ReO4]- is colorless. This is due to greater energy required for 1. d-d transitions in the Re compound compared to the Mn compound 2. d-d transitions in the Mn compound compared to the Re compound 3. charge transfer from O to Re compared to O to Mn 4. charge transfer from O to Mn compared to O to Re.
