Accepted Answer

$\left[\mathrm{Cr}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{3+}< \left[\mathrm{Cr}\left(\mathrm{NH}_3\right)_6\right]^{3+}< \left[\mathrm{Cr}(\mathrm{CN})_6\right]^{3-}$

Answer

$\left[\mathrm{Cr}\left(\mathrm{NH}_3\right)_6\right]^{3+}< \left[\mathrm{Cr}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{3+}< \left[\mathrm{Cr}(\mathrm{CN})_6\right]^{3-}$

Answer

$\left[\mathrm{Cr}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{3+}>\left[\mathrm{Cr}\left(\mathrm{NH}_3\right)_6\right]^{3+}>\left[\mathrm{Cr}(\mathrm{CN})_6\right]^{3-}$

Answer

$\left[\mathrm{Cr}\left(\mathrm{NH}_3\right)_6\right]^{3+}< \left[\mathrm{Cr}(\mathrm{CN})_6\right]^{3-}< \left[\mathrm{Cr}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{3+}$
