A) \[{{[Mn{{({{H}_{2}}O)}_{6}}]}^{3+}}\]
B) \[{{[Fe{{({{H}_{2}}O)}_{6}}]}^{3+}}\]
C) \[{{[Co{{({{H}_{2}}O)}_{6}}]}^{2+}}\]
D) \[{{[Co{{({{H}_{2}}O)}_{6}}]}^{3+}}\]
Correct Answer: B
Solution :
[b]: \[{{H}_{2}}O\]is a weak field ligand, hence \[{{\Delta }_{0}}<\]pairing energy.\[CFSE=(-0.4x+0.6y){{\Delta }_{0}}\]where, x and y are no. of electrons occupying\[{{t}_{2g}}\]and \[{{e}_{g}}\] orbitals respectively. For \[{{[Fe{{({{H}_{2}}O)}_{3}}]}^{3+}}\]complex ion, \[F{{e}^{3+}}[3{{d}^{5}}]:t_{2g}^{3}e_{g}^{2}=-0.4\times 3+0.6\times 2=0.0\]or 0 DqYou need to login to perform this action.
