Chapter 23, Problem 43E

Interpretation Introduction

Interpretation:

‘Crystal field splitting energys’ should be identified.

Concept introduction:

Weak field ligand is present in the given complex which results in unpaired electron because very less energy is absorbed by these complex and the CFSE can be calculated with the wavelength as follows;

$\text{E}\text{=}\frac{\text{hc}}{\text{λ}}$

where,

h is planks constant

c is speed of light

λ is wavelength.

Given:

Wavelength of 735 nm for [CrC1₆]^3- ion.
