A) \[{{[Cr{{(CN)}_{6}}]}^{3-}}\]
B) \[{{[Co{{(N{{H}_{3}})}_{6}}]}^{3+}}\]
C) \[{{[CoC{{l}_{6}}]}^{3-}}\]
D) \[{{[Cr{{({{H}_{2}}O)}_{6}}]}^{3+}}\]
Correct Answer: C
Solution :
\[{{[Cr{{(CN)}_{6}}]}^{3-}}\] \[C{{r}^{3+}}:{{d}^{3}}:{{t}^{3}}_{2g}{{e}^{0}}g=-1.2{{\Delta }_{0}}\] \[{{[Co{{(N{{H}_{3}})}_{6}}]}^{3+}}\] \[C{{o}^{3+}}:{{d}^{6}}:{{t}^{6}}_{2g}{{e}^{0}}_{g}=-2.4{{\Delta }_{0}}\] \[{{[CoC{{l}_{6}}]}^{3-}}\] \[C{{o}^{3+}}:{{d}^{6}}:{{t}^{4}}_{2g}{{e}^{2}}_{g}-0.4{{\Delta }_{0}}\] \[{{[Cr{{({{H}_{2}}O)}_{6}}]}^{3+}}\] \[C{{r}^{3+}}:{{d}^{3}}:{{t}^{3}}_{2g}{{e}^{0}}_{g}=-1.2{{\Delta }_{0}}\] The minimum magnitude of \[{{\Delta }_{0}}\]IS FOR \[{{[CoC{{l}_{6}}]}^{3-}}.\] Hence, the correct option is [c].
