Which one of the following elements is unable to form $M F_{6}^{3 -}$ ion?

Options:

Answer:

Solution:

As ‘B’ has no d-orbitals, so it can’t extend its covalency beyond 4. Hence, ‘B’ cannot form the ion like ${MF}_{6}^{3 -}$ , i.e., ${BF}_{6}^{3 -}$ .
As all other metals have vacant d-orbitals in their valence shells, so they can extend their covalency beyond 4.
