ChemistryNEET 2019Potassium dichromate and permanganate

The d- and f-Block Elements

The manganate (MnO42−\mathrm{MnO_4^{2-}}) and permanganate (MnO4−\mathrm{MnO_4^-}) ions are tetrahedral, due to:

  1. A.π\pi-bonding involving overlap of p-orbitals of oxygen with d-orbitals of manganese✓
  2. B.The absence of any π\pi-bonding
  3. C.π\pi-bonding involving overlap of p-orbitals of oxygen with p-orbitals of manganese
  4. D.π\pi-bonding involving overlap of d-orbitals of oxygen with d-orbitals of manganese

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
