Which does not give a precipitate with (AgNO_3) solution?
Which does not give a precipitate with (\mathrm{AgNO}_3) solution?
Options
- A(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right] \mathrm{Cl}_3)
- B(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5 \mathrm{Cl}\right] \mathrm{Cl}_2)
- C(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right] \mathrm{Cl})
- D(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_3 \mathrm{Cl}_3\right])
Correct answer
D. (\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_3 \mathrm{Cl}_3\right])
Step-by-step solution
(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_3 \mathrm{Cl}_3\right]) does not give a precipitate with (\mathrm{AgNO}_3) solution because in it all the chlorine atoms are attached by secondary valencies.
