Which one of the following does not give a white precipitate with silver nitrate solution?

A$$[Co(NH_3)_6]Cl_3$$
B$$[Co(NH_3)_5Cl]Cl_2$$
C$$[Co(NH_3)_4Cl_2]Cl_2$$
D$$[Pt(NH_3)_3Cl_2]Cl$$
Correct Answer

Solution

The coordination number of Platinum is six.

Therefore, formula is $$[Pt(NH_{3})_{3}Cl_{3}]$$.

The complex can give a white precipitate with $$AgNO_{3}$$ if $$Cl$$ ions are present as counter ion i.e. outside the square bracket. As $$[Pt(NH_{3})_{3}Cl_{3}]$$ doesn't contain any chloride ions as counter ions it does not give a precipitate with silver nitrate to form a white ppt.

Hence,correct option is (D).
