If one mole of PtCl2·3NH3 reacts with AgNO3 to produce one mole of AgCl(s), how can the formula PtCl2·3NH3 be re-written to show the proper coordination sphere?
a) [Pt(NH3)3Cl2]
b) [Pt(NH3)3Cl]Cl
c) [Pt(NH3)3Cl3]-
d) [Pt(NH3)3]Cl2

Answer :

The correct answer is b) [Pt(NH₃)₃Cl]Cl
Due to:
Chloride ion which is present outside the co-ordination sphere will react with AgNO₃ & since the reaction produces only one mole of AgCl so one Cl only outside the sphere and the formula is: [Pt(NH₃)₃Cl]Cl
