Question

Given below are two statements:
Statement I : Potassium permanganate on heating at $573\, K$ forms potassium manganate.
Statement II : Both potassium permanganate and potassium manganate are tetrahedral and paramagnetic in nature. In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Statement I is true but statement II is false
• B. Both statement I and statement II are true
• C. Statement I is false but statement II is true
• D. Both statement I and statement II are false

Answer 1

Answer: (A)

$\underset{\text{Potassium permanganate}}{2KMnO_4} \xrightarrow{573\,K} \underset{\text{Potassium manganate}}{K_{2}MnO_{4}}+MnO_{2} +O_{2}$


Statement-I is correct.

Statement-II is incorrect
