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

  1. A \(3\,AgCl, \,\,1\,AgCl, \,\,2\,AgCl\)
  2. B \(3\,AgCl, \,\,2\,AgCl, \,\,1\,AgCl\)
  3. C \(2\,AgCl,\,\, 3\,AgCl, \,\,2\,AgCl\)
  4. D \(1\,AgCl,\,\, 3\,AgCl, \,\,2\,AgCl\)

Answer & Solution

Correct Answer

(B) \(3\,AgCl, \,\,2\,AgCl, \,\,1\,AgCl\)

Step-by-step Solution

Detailed explanation

\(\left[\mathrm{CO}\left(\mathrm{NH}_{3}\right)_{6}\right] \mathrm{Cl}_{3} \stackrel{\mathrm{AgNO}_{3}}{\longrightarrow} 3\,\mathrm{mol}\;\mathrm{AgCl}\) \([\mathrm{CO}\left(\mathrm{NH}_{3}\right)_{5} \mathrm{Cl}] \mathrm{Cl}_{2} \stackrel{\mathrm{AgNO}_{3}}{\longrightarrow} 2\, \mathrm{mol}\; \mathrm{AgCl}\)
