MCQ
  • A
    $X=\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{2+} 3 \mathrm{Cl}^{-}, \mathrm{Y}=1: 3$
  • $X=\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+} \mathrm{Cl},-\mathrm{Y}=1: 3$
  • C
    $X=\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+} \mathrm{Cl}^{-}, \mathrm{Y}=1: 1$
  • D
    $X=\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{3+} 3 \mathrm{Cl}^{-}, \mathrm{Y}=1: 1$

Answer

Correct option: B.
$X=\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+} \mathrm{Cl},-\mathrm{Y}=1: 3$
(b) $\mathrm{X}=\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+} \mathrm{Cl}^{-}, \quad \mathrm{Y}=1: 3$
