Question
Which of the following statements is/are correct ?
Options
A.The stability constant of [Co(NH3)6]3+ is greater than that of [Co(NH3)6]2+.
B.Among F-, Cl-, Br- and I-, F- forms strongest complexes due to small size.
C.[Cu(NH3)4]2+ is thermodynamicaly more stable than [Zn(NH3)4]2+.
D.Among [Fe(CN)6]3-, [Fe(H2O)6]2+ and [Fe(en)3]3+, [Fe(CN)6]3- is most stable.
Solution
(A) For a given metal and ligand the stability is greater when the charge on the metal ion is greater; as oxidation state increases size of cation decreases.
(B) F- forms strongest complex. Smaller the size of the anion, greater the charge density on the atom and hence greater the sability of complex.
(C) Smaller the size of the metal ion, greater is the stability of the complex.
(D) Complex having chelate rings is more stable.
(B) F- forms strongest complex. Smaller the size of the anion, greater the charge density on the atom and hence greater the sability of complex.
(C) Smaller the size of the metal ion, greater is the stability of the complex.
(D) Complex having chelate rings is more stable.
