Chapter 9, Problem 9D.1BST

Interpretation Introduction

Interpretation:

The ligand field splitting energy of the complex ${\left[\text{Fe}{\left(\text{CN}\right)}_{\text{6}}\right]}^{\text{4-}}$ has to be given.

Concept Introduction:

The ligand field splitting energy of the complex can be calculated using the following formula,

  ${\text{Δ}}_{\text{o}}\text{=}\frac{{\text{N}}_{\text{A}}\text{hc}}{\text{λ}}$

Where ${\text{Δ}}_{\text{o}}$ is the ligand splitting energy of an octahedral complex.

${\text{N}}_{\text{A}}$ is the Avogadro’s number $\left(\text{6}{\text{.022×10}}^{\text{23}}{\text{mol}}^{\text{-1}}\right)$

h is the Planck’s constant $\left(\text{6}{\text{.626×10}}^{\text{-34}}{\text{Js}}^{\text{-1}}\right)$

c is the velocity of the light $\left({\text{3×10}}^{\text{8}}{\text{ms}}^{\text{-1}}\right)$

$\text{λ}$ is the wavelength of the light absorbed.
