Given below are two statements :
Statement I : Potassium permanganate on heating at 573K 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 :
Solution
<b>Statement-1</b> : KMnO<sub>4</sub> $\buildrel {573K} \over
\longrightarrow$ K<sub>2</sub>MnO<sub>4</sub> + MnO<sub>2</sub> + O<sub>2</sub><br><br>
<b>Statement-2</b> :<br> KMnO4 $\Rightarrow$ Mn<sup>7+</sup> $\Rightarrow$ Diamagnetic.<br>
KMnO<sub>4</sub> $\Rightarrow$ Mn<sup>6+</sup> $\Rightarrow$ Paramagnetic.
