Chapter 22, Problem 27QP

Interpretation Introduction

Interpretation:

The terms “crystal field splitting,” “high-spin complex,” “low-spin complex,” and “spectrochemical series” are to be defined.

Concept Introduction:

The crystal field theory explains the coloring and magnetic properties of the coordination compounds and ions through the bonding of metals and ligands through electrostatic forces. Coordination complexes witness two types of forces: one is electrostatic attraction between the metal atom and the ligand and the other is the electrostatic repulsion between the $d\text{ orbital}$ electrons and the lone pair on the ligand(s).
