Q. One mole of the complex compound $Co\left( {NH}_{3} \right)5{Cl}_{3}$, gives 3 moles of ions on dissolution in water . One mole of the same complex reacts with two moles of ${AgNO}_{3}$solution to yield two moles of AgCl(s). The structure of the complex is

A) $\left\lbrack Co\left( {NH}_{3} \right)_{5}Cl \right\rbrack{Cl}_{2}$
B) $\left\lbrack Co\left( {NH}_{3} \right)_{3}{Cl}_{2} \right\rbrack.2{NH}_{3}$
C) $\lbrack Co\left( {NH}_{3} \right)_{4}{Cl}_{2}\rbrack Cl.{NH}_{3}$
D) $\left\lbrack Co\left( {NH}_{3} \right)_{4}Cl \right\rbrack{Cl}_{2}.{NH}_{3}$
Explanation

The correct answer is Option A: $\left\lbrack Co\left( {NH}_{3} \right)_{5}Cl \right\rbrack{Cl}_{2}$.
