Question

what is the importance of spectrochemical series

Answer 1

Answer:

The spectrochemical series is a convenient way of organizing ligands by field strength. Ligands affect the d electrons of metals, splitting degenerate energy levels into more organized levels of energy.

Answer 2

Spectrochemical series help in predicting the relative splitting of metal complexes with the same metal ion and different ligands.

• The spectrochemical series was established in 1938.
• In spectrochemical series, ligands are arranged based on their strength.
• Ligands are arranged from large splitting values to lower splitting values.
• CN⁻, CO, NO₂⁻, en, NH₃, H₂O, Oxalane, OH⁻, F⁻, SCN⁻, Cl⁻, Br⁻, and I⁻ is the spectrochemical series for ligands.
• It gives an easy understanding of the weak field and strong field ligands.
• Strong field ligands cause more crystal field splitting than weak field ligands.
• The splitting of the degenerate d orbitals of the metal ion in the presence of ligands is known as crystal field splitting.
• A metal complex consists of one central metal ion and ligands attached to it.
• The central metal ion will have 5 degenerate presences, in the presence of ligands, the degenerate d orbitals undergo splitting.
• The extent to which the splitting happens depends upon the strength of the ligand.
• The strength of the ligand can be understood from the spectrochemical series.
