Vedclass · Answer

(A) The stability of a coordination complex depends on several factors,including the nature of the ligand and the oxidation state of the central metal ion.$1$. Strong field ligands like $CN^-$ form more stable complexes compared to weak field ligands like $H_2O$.$2$. $A$ higher positive oxidation state of the central metal ion generally leads to greater stability due to stronger electrostatic attraction.$3$. In $[Co(CN)_6]^{3-}$,the cobalt ion is in the $+3$ oxidation state and is coordinated by six strong $CN^-$ ligands,resulting in high crystal field splitting energy and maximum stability.

Which of the following complexes represents maximum stability?
