The manganate and permanganate ions are tetrahedral , due to

The manganate and permanganate ions are tetrahedral, due to

(1) The π-bonding involves overlap of p-orbitals of oxygen with d-orbitals of manganese.
(2) There is no π-bonding.
(3) The π-bonding involves overlap of p-orbitals of oxygen with p-orbitals of manganese.
(4) The π-bonding involves overlap of d-orbitals of oxygen with d-orbitals of manganese.
Answer : from all above options the correct answer is “(1) The π-bonding involves overlap of p-orbitals of oxygen with d-orbitals of manganese.
Answer explanation : In manganate and paramanganate , the π bonding involves the overlap of p-orbitals of oxygen with d-orbitals of manganese which leads to their tetrahedral structure. the structure is draw as follows given below –
as we know that in manganate and permanganate ions π-bonding contains overlap of p-orbitals of oxygen with d-orbitals of manganese , that is why the correct answer is option (1)
