    \[C{{N}^{-}}\] is a strong field ligand. This is due to the fact that [CBSE PMT 2004]

    A) It can accept electron from metal species

    B) It forms high spin complexes with metal species

    C) It carries negative charge.

    D) It is a pseudohalide

    Correct Answer: D

    Solution :

    Cyanide ion is strong field ligand because it is a pseudohalide ion pseudohalide ions are stronger coordinating ligand & they have the ability to form \[\sigma \] bond (from the pseudohalide to the metal) and \[\pi \] bond (from the metal to pseudohalide).
