Chapter 21, Problem 10Q

(a)

Interpretation Introduction

Interpretation: The given diagrams are to be labeled as low spin, high spin, or cannot tell with proper explanation.

Concept introduction: Weak field ligand that has small crystal field splitting energy gives high spin due to presence of maximum unpaired electrons in lower energy ${\text{t}}_{\text{2g}}$ orbitals and higher energy orbitals.

Strong field ligand that has large crystal field splitting energy gives low spin due to presence of maximum paired electrons in lower energy ${\text{t}}_{\text{2g}}$ orbitals.

To label: The given diagram as low spin, high spins, or cannot tell with proper explanation.
