Solution

The correct option is A $[C o (N H_{3})_{6}] C l_{3}$
In the given complex compound the chlorine present within the coordination sphere won't react with $A g N O_{3}$ . However Chlorine present outside the coordination sphere reacts with the $A g N O_{3}$ and produces AgCl.

When one mole of each of the following complexes is treated with excess of $A g N O_{3}$ , $[C o (N H_{3})_{6}] C l_{3}$ will give maximum amount of $A g C l$ .

$[C o (N H_{3})_{6}] C l_{3} + 3 A g N O_{3} \to [C o (N H_{3})_{6}] (N O_{3})_{3} + 3 A g C l ↓$

$[C o (N H_{3})_{6}] C l_{3}$ gives 3 moles of $A g C l$ .

$[C o (N H_{3})_{5} C l] C l_{2}$ gives 2 moles of $A g C l$ .

$[C o (N H_{3})_{4} C l_{2}] C l$ gives 1 mole of $A g C l$ .

$[C o (N H_{3})_{3} C l_{3}]$ will not give $A g C l$ .

Hence, option A is the correct answer.
