Potassium Permanganate

24.Which of the following statement(s) is/are correct regarding manganate and permanganate ions? A) All the pi -bonds in manganate and permanganate are formed by the overlap of "p" -orbitals of oxygen and "d" -orbitals of manganese.B) Manganate ion is paramagnetic due to presence of unpaired electron in "p" orbital.C) Permanganate is diamagnetic but becomes paramagnetic on heating. D) The tetrahedral structure of both manganate and permanganate is due to sp^(3) hybridisation.
