One mole of complex compound 'Co(NH₃)₅Cl₃ gives 3 moles of ions on dissolution in water. One mole of the same complex reacts with 2 moles of AgNO₃ solution to yield 2 moles of AgCl .The structure of the complex is

Options

A. `[Cr(NH_3)_4 Cl]Cl_2. NH_3`
B. `[Cr(NH_3)_4Cl_2] Cl.NH_3`
C. `[Cr(NH_3)_5Cl]Cl_2`
D. `[Cr(NH_3)_3 Cl_3] . 2NH_3`

Answer

C

Explanation

`[Cr(NH_3)_5Cl]Cl_2 overset(H_2O)to [Cr(NH_5)_5Cl]^(2+) + 2Cl^(Theta)`
`2AgNO_3 + 2Cl^(Theta)to 2AgCl + 2NH_3^(Theta)`
