WebCyanide ion is a strong ligand. It will cause greater splitting between the respective orbitals. In case of strong ligands, pairing of electrons will be higher. Therefore, they are low-spin complexes. Therefore, strong field ligands such as cyanide produce low spin complexes and high field splitting. Therefore, the correct option is (c). notes on hypothesisWeb(II) Ni(II) complex can very rarely be low spin. (III) with strong field ligands, Mn(II) complexes can be low spin.
