In the spectrochemical series, which one of the following ligands has the strongest field? A)H ₂O B)CN ⁻ C)NH ₃ D)OH ⁻ E)Cl ⁻

Question

Quizplus · Accepted Answer

In the spectrochemical series, ligands are arranged in increasing order of their field strength. CN- is known to be a strong field ligand because it has a negative charge and is small in size. This causes a greater splitting of the d-orbitals in the metal ion, leading to a higher crystal field stabilization energy (CFSE). Therefore, among the given options, choice B with CN- is the strongest field ligand.
