Chapter 11, Problem 11F.10AE

Interpretation Introduction

Interpretation:

The value of ${\Delta }_{\text{O}}$ for the complex ion, ${\left[\text{Fe}{\left({\text{OH}}_{\text{2}}\right)}_{\text{6}}\right]}^{3+}$ has to be estimated.

Concept introduction:

Electronic spectra arise out of the transitions between the electronic energy levels of the molecule.  In a free atom, all five $\text{d}$ orbitals are degenerate.  In a $\text{d-}$ metal complex, the degeneracy of the $\text{d}$ orbitals is destroyed and electrons absorb energy to make transitions.
