$CN^{-}$

Vedclass · Answer

(A) The spectrochemical series classifies ligands based on their ability to cause crystal field splitting. $CN^{-}$ is a strong field ligand because it is capable of causing large crystal field splitting,denoted by a high value of $\Delta_o$. While $NO_2^{-}$,$en$,and $NH_3$ are also considered strong field ligands relative to halides,$CN^{-}$ is typically placed at the extreme end of the strong field side in the spectrochemical series.

Which one of the following is a strong field ligand?
