Vedclass · Answer

(C) The stability of coordination complexes is influenced by the nature of the ligand and the crystal field splitting energy. Among the given complexes,$[Fe(CN)_6]^{4-}$ is the most stable. $CN^-$ is a strong field ligand that causes large crystal field splitting,leading to a low-spin $d^6$ configuration for $Fe^{2+}$. This results in a high crystal field stabilization energy $(CFSE)$. While $[Fe(CN)_6]^{3-}$ is also stable,$[Fe(CN)_6]^{4-}$ is generally considered more stable due to the higher charge density and stronger back-bonding associated with the $Fe^{2+}$ state in this specific geometry.
