Q. The manganate and permanganate ions are tetrahedral, due to
A) The $\pi$-bonding involves overlap of p-orbitals of oxygen with d-orbitals of manganese
B) There is no $\pi$-bonding
C) The $\pi$-bonding involves overlap of p-orbitals of oxygen with p-orbitals of managanese
D) The $\pi$-bonding involves overlap of d-orbitals of oxygen with d-orbitals of manganese
Explanation
[Solution] In $MnO_4^{2-}$ and $MnO_4^-$, $\pi$ bonding arises from overlap of oxygen p orbitals with manganese d orbitals. Answer (1).
