Question:
Out of KMnO$_4$ and K$_2$MnO$_4$, which one is paramagnetic and why?
Out of KMnO$_4$ and K$_2$MnO$_4$, which one is paramagnetic and why?
Show Hint
Check d-electrons → unpaired means paramagnetic.

Solution and Explanation
KMnO$_4$: Mn in +7 → d$^0$ → diamagnetic.
K$_2$MnO$_4$: Mn in +6 → d$^1$ → 1 unpaired → paramagnetic.
K$_2$MnO$_4$: Mn in +6 → d$^1$ → 1 unpaired → paramagnetic.
