The green paramagnetic species formed by heating KMnO4 at 513 K is

  1. A
    K2MnO4
  2. B
    Mn3O4
  3. C
    MnO
  4. D
    KO2

Correct answer · Option A

K2MnO4

Explanation

Thermal decomposition of potassium permanganate at 513 K yields potassium manganate (K2MnO4), which is green and paramagnetic due to unpaired electrons in MnO4 2-.
