Question

One mole of the complex compound $Co{\left(N{H}_3\right)}_5{Cl}_3$, gives 3 moles of ions on dissolution in water. One mole of the same complex reacts with two moles of $AgN{O}_3$ solution to yield two moles of $AgCl\left(s\right)$. The structure of the complex is :

• A. $\left[Co{\left(N{H}_3\right)}_3{Cl}_3\right]\cdot 2N{H}_3$
• B. $\left[Co{\left(N{H}_3\right)}_4{Cl}_2\right]Cl\cdot N{H}_3$
• C. $\left[Co{\left(N{H}_3\right)}_{4}Cl\right]{Cl}_2\cdot N{H}_3$
• D. $\left[Co{\left(N{H}_3\right)}_{5}Cl\right]{Cl}_2$

Answer 1

The correct option is D $\left[Co{\left(N{H}_3\right)}_{5}Cl\right]{Cl}_2$
