One mole of the octahedral complex compound $Co(NH_3)_5Cl_3$ gives $3$ moles of ions on dissolution in water. One mole of the same complex reacts with excess of $AgNO_3$ solution to yield two moles of $AgCl_{(s)}$. The structure of the complex is :
- A$[Co(NH_3)_5Cl]Cl_2$
- B$[Co(NH_3)_4Cl] \cdot Cl_2 \cdot NH_3$
- C$[Co(NH_3)_4Cl_2]Cl \cdot NH_3$
- D$[Co(NH_3)_3Cl_3] \cdot 2NH_3$
