What are the various factors affecting crystal field splitting

Posted by Neeraj Kumar Agrawal 6 years ago

CBSE > Class 12 > Chemistry

1 answers

Yogita Ingle 6 years ago

Factors affecting crystal field splitting energy:

1) The coordination geometry and number of ligands around the metal ion- Generally, the tetrahedral field produce smaller spilling than octahedral field.
2) The nature of the ligands - Strong field ligands cause more splitting than weak field ligands.
3) The oxidation state of metals- Higher is the oxidation state of the central metal ion, greater is the crystal field splitting.
