Vedclass · Answer

(B) The thermodynamic stability of a coordination complex is primarily determined by the charge density of the central metal ion. Higher charge on the central metal ion leads to stronger electrostatic attraction with the ligands,resulting in higher stability. The oxidation states of the central metal ions in the given complexes are: $Co$ in $[Co(NH_3)_6]^{3+}$ is $+3$. $Cu$ in $[Cu(CN)_4]^{2-}$ is $+2$. $Ag$ in $[Ag(CN)_2]^{-}$ is $+1$. Therefore,the order of stability follows the order of oxidation states: $[Co(NH_3)_6]^{3+} > [Cu(CN)_4]^{2-} > [Ag(CN)_2]^{-}$.

Which among the following is a correct decreasing order of thermodynamic stability of the complexes?
