Chapter 20, Problem 12Q

(a)

Interpretation Introduction

Interpretation: The complex ion, the counter ions, the electronic configuration of the transition metal and geometry of complex ion for each of the given coordination compounds is to be stated.

Concept introduction: The electrons in the d orbital of a transition metal split into high and low energy orbitals when ligands are attached to it. The energy difference between these two levels depends upon the properties of both metal and the ligands. If the ligand is strong, then splitting will be high and the complex will be low spin. If the ligand is weak, then splitting will be less and the complex will be high spin.

To determine: The complex ion, the counter ions, the electronic configuration of the transition metal and geometry of complex ion for the given coordination compound.
