One mole of the complex compound Co ( NH 3)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) [ Co ( NH 3)5 Cl ] Cl 2 (B) [ Co ( NH 3)3 Cl 2] ⋅ 2 NH 3 (C) [ Co ( NH 3)4 Cl 2] Cl ⋅ NH 3 (D) [ Co ( NH 3)4 Cl ] Cl 2 ⋅ NH 3

Q. One mole of the complex compound $C o (N H_{3})_{5} C l_{3}$ , gives 3 moles of ions on dissolution in water. One mole of the same complex reacts with two moles of $A g N O_{3}$ solution to yield two moles of $A g Cl (s)$ . The structure of the complex is :

$[C o (N H_{3})_{5} Cl] C l_{2}$

$[C o (N H_{3})_{3} C l_{2}] \cdot 2 N H_{3}$

$[C o (N H_{3})_{4} C l_{2}] Cl \cdot N H_{3}$

$[C o (N H_{3})_{4} Cl] C l_{2} \cdot N H_{3}$

$C o (N H_{3})_{5} Cl] C l_{2} ⇌ three ions [C o (N H_{3})_{5} Cl]^{2 +} + 2 C l^{-}$

$free 2 mol 2 C l^{-} + 2 mol 2 A g^{+} + \to 2 mol 2 A g Cl$
