Question

One mole of the octahedral compound Co(NH3)5Cl3 gives 3 moles of ions on dissolution in water. One mole of the same complex reacts with excess of AgNO3 solution to yield two moles of AgCl(s). The structure of the complex is:

(A) [Co(NH3)4Cl].Cl2.NH3
(B) [Co(NH3)3 Cl3].2NH3
(C) [Co(NH3)5Cl]Cl2
(D) [Co(NH3)4Cl2].Cl.NH3
