What is the spectrochemical series? Explain the difference between a weak field ligand and a strong field ligand.
What is the spectrochemical series? Explain the difference between a weak field ligand and a strong field ligand.

The Spectrochemical series is a set of common ligands arranged in ascending order of their crystal-field splitting energy (CFSE).

CFSE readings are higher in strong field ligands. Weak field ligands, on the other hand, have lower CFSE values.
