NEET · Chemistry · STD 12 - 5. Co-ordination chemistry
The correct order of the stoichiometries of \(AgCl\) formed when \(AgNO_3\) in excess is treated with the complexes : \(CoCl_3 \cdot 6NH_3, CoCl_3 \cdot 5NH_3,CoCl_3\cdot 4NH_3\) respectively is
- A \(3\,AgCl, \,\,1\,AgCl, \,\,2\,AgCl\)
- B \(3\,AgCl, \,\,2\,AgCl, \,\,1\,AgCl\)
- C \(2\,AgCl,\,\, 3\,AgCl, \,\,2\,AgCl\)
