Spectrochemical Series
In the spectrochemical series, the correct order of ligand strength is:
Select the correct option:
Solution
I⁻ < Br⁻ < Cl⁻ < F⁻ and CN⁻ (strongest)
The Spectrochemical Series arranges ligands based on their ability to split d-orbitals (Δ value): I−<Br−<SCN−<Cl−<S2−<F−<OH−<C2O42−<H2O<NCS−<edta4−<NH3<en<NO2−<CN−<CO
- Weak Field Ligands: (I,Br,Cl,F,H2O) cause small splitting.
- Strong Field Ligands: (NH3,en,CN−,CO) cause large splitting and often result in electron pairing.
