On heating potassium permanganate, one of the following compound is not obtained:

Options

  1. A( O ₂ )
  2. B( MnO )
  3. C( MnO ₂ )
  4. D( K ₂ MnO ₄ )

Correct answer

B. ( MnO )

Step-by-step solution

Heating of potassium permanganate salt at ( 513 ~K ) ( 2 KMnO ₄⁻-> K ₂ MnO ₄+ MnO ₂+ O ₂ ) Hence, on heating of potassium permanganate, MnO will not be obtain.
