Question

How many unpaired e${}^{\Theta }$ are present in e${}_g$ orbital of MnO${}_4^{-}$ ?

• A. 0

Answer 1

The correct option is A 0
Zero unpaired e${}^{\Theta }$ are present in e${}_g$ orbital of MnO${}_4^{-}$. The oxidation state of Mn is +7. Th outer electronic configuration is $3d^0$ which can also be written as $t_{2g}^0{e}_g^0$.
