The most likely crystal field diagram of the given complex ion needs to be determined. Concept Introduction: Crystal field theory is the theory given to explain the bonding in the coordination complexes. As ligand approaches towards the metal ion, the d-orbital of metal ion divide according to the energy of metal ion. On the basis of energy and degeneracy, the d-orbital can be classified as t 2g and e g orbitals. The electrons will fill according to their energy levels. In octahedral complex, the t 2g orbitals are lower energy orbitals in d-orbital splitting whereas e g orbitals are higher energy orbitals.

Chapter 19, Problem 100CP

Interpretation Introduction

Interpretation: The most likely crystal field diagram of the given complex ion needs to be determined.

Concept Introduction:

Crystal field theory is the theory given to explain the bonding in the coordination complexes. As ligand approaches towards the metal ion, the d-orbital of metal ion divide according to the energy of metal ion. On the basis of energy and degeneracy, the d-orbital can be classified as t2g and eg orbitals. The electrons will fill according to their energy levels.

In octahedral complex, the t2g orbitals are lower energy orbitals in d-orbital splitting whereas eg orbitals are higher energy orbitals.
