Why is the green manganate paramagnetic, while the permanganate is diamagnetic?

Options

  1. AThe manganate has an unpaired electron, while the permanganate does not.
  2. BThe manganate has a lower oxidation state of manganese.
  3. CThe manganate has a higher solubility in water.
  4. DThe manganate has a higher temperature-dependent weak paramagnetism.

Correct answer

A. The manganate has an unpaired electron, while the permanganate does not.

Step-by-step solution

The green manganate is paramagnetic because of one unpaired electron, while the permanganate is diamagnetic due to the absence of an unpaired electron.
