Question

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

• A. $O_2$
• B. $MnO$
• C. $MnO_2$
• D. $K_2MnO_4$

Answer 1

Answer: (B)

$MnO$

Answer 2

When heated . potassium permanganate decomposes at $513 \,K$ $\underset{\text{Patassium permanganate }}{{2KMnO_4}} { ->[{\text{Heat}}][{513 K}] } \underset{\text{Potassium manganate }}{{K_2MnO_4}}+MnO_2+O_2$ So, MnO is not obtained
