Chapter 21, Problem 37RQ

Interpretation Introduction

Interpretation:

Octahedral cobalt(II) complexes are easily oxidized to cobalt(III) complexes is to be explained. The five different $d$-orbitals of a $d$ subshell are to be sketched with the assumption that a large value of $\Delta$ when placing electrons in the $d$ orbitals.

Concept Information:

Crystal field theory is the theory that explains the bonding of complex ions.

Ligands are molecules or ions that are bonded with a coordinate covalent bond to a metal ion.

The Crystal Field Stabilization Energy (CFSE) is the energy generated by distributing the electrons in the $d$-orbitals of a transition metal ion in the crystal field caused by ligands.
