Question

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

Ga

Al

In

B

Solution

The element M in the complex-ion $M F_{6}^{- 3}$ has a coordination number of six.

B has only s and p-orbitals and no d – orbitals available, therefore, at the maximum it can show a coordination number of 4. Thus, B cannot form the complex of the type $M F_{6}^{- 3}$
