$CN^{-}$

Vedclass · Answer

(A) According to the spectrochemical series,the strength of ligands is determined by their ability to cause crystal field splitting. $CN^{-}$ is a strong field ligand because it is a $\pi$-acceptor ligand,which forms strong $\sigma$-bonds and $\pi$-back bonds with the metal center. $Br^{-}$,$HO^{-}$,and $F^{-}$ are weak field ligands (halides and oxygen donors). Therefore,$CN^{-}$ is the strongest ligand among the given options.
