Solution


Q.

The manganate and permanganate ions are tetrahedral, due to            [2019]
1 the π-bonding involves overlap of d-orbitals of oxygen with d-orbitals of manganese  
2 the π-bonding involves overlap of p-orbitals of oxygen with d-orbitals of manganese  
3 there is no π-bonding  
4 the π-bonding involves overlap of p-orbitals of oxygen with p-orbitals of manganese.  

Ans.

(2)

In manganate and permanganate ions, π-bonding takes place by overlap of p-orbitals of oxygen with d-orbitals of manganese.
