Which among the following coordination compound does not give white precipitate of $\text{AgCl}$ when treated with $\text{AgNO}_3$ solution?
- a$\text{CoCl}_3\cdot6\text{NH}_3$
- b$\text{CoCl}_3\cdot5\text{NH}_3$
- c$\text{CoCl}_3\cdot4\text{NH}_3$
- d$\text{CoCl}_3\cdot3\text{NH}_3$

Correct option: d
Answer: (d) $\text{CoCl}_3\cdot3\text{NH}_3$
In $[\text{Co}(\text{NH}_3)_3\text{Cl}_3]$, all three chloride ions are within the coordination sphere and do not ionise, so no precipitate of $\text{AgCl}$ forms.
