Options
- A\left[\mathrm{Ni}\left(\mathrm{NO}_2\right)_6\right]^{4-} < \left[\mathrm{Ni}\left(\mathrm{NH}_3\right)_6\right]^{2+} < \left[\mathrm{Ni}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{2+}
- B\left[\mathrm{Ni}\left(\mathrm{NO}_2\right)_6\right]^{4-} < \left[\mathrm{Ni}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{2+} < \left[\mathrm{Ni}\left(\mathrm{NH}_3\right)_6\right]^{2+}
- C\left[\mathrm{Ni}\left(\mathrm{H}_2 \mathrm{O}_6\right]^{2+} < \left[\mathrm{Ni}\left(\mathrm{NH}_3\right)_6\right]^{2+} < \left[\mathrm{Ni}\left(\mathrm{NO}_2\right)_6\right]^{4-}\right.
- D\left[\mathrm{Ni}\left(\mathrm{NH}_3\right)_6\right]^{2+} < \left[\mathrm{Ni}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{2+} < \left[\mathrm{Ni}\left(\mathrm{NO}_2\right)_6\right]^{4-}
Correct answer
A. \left[\mathrm{Ni}\left(\mathrm{NO}_2\right)_6\right]^{4-} < \left[\mathrm{Ni}\left(\mathrm{NH}_3\right)_6\right]^{2+} < \left[\mathrm{Ni}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{2+}
