Chapter 20, Problem 3ALQ

Interpretation Introduction

Interpretation: The paramagnetic or diamagnetic behaviour of the given metal complexes ${\left[\text{Fe}{\left(\text{CN}\right)}_6\right]}^{4-}$ and ${\left[\text{Fe}{\left({\text{H}}_2\text{O}\right)}_6\right]}^{2+}$ is to be stated.

Concept introduction: The strong-field ligands lead to pairing of electrons and lead to diamagnetic species, while the low-field ligand do not have tendency to pair up the electrons and therefore forms paramagnetic species.

To determine: The paramagnetic or diamagnetic behavior of the given complexes ${\left[\text{Fe}{\left(\text{CN}\right)}_6\right]}^{4-}$ and ${\left[\text{Fe}{\left({\text{H}}_2\text{O}\right)}_6\right]}^{2+}$.
