Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
Which of the following are outer orbital octahedral complexes? (1) \[{{[Fe{{F}_{6}}]}^{3-}}\] \[{{[Fe{{(CN)}_{6}}]}^{4-}}\] \[{{[Fe{{({{H}_{2}}O)}_{6}}]}^{2+}}\] \[{{[Fe{{(CN)}_{6}}]}^{3-}}\]A) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: D
Solution :
Weak field ligands like\[{{F}^{-}},\text{ }{{H}_{2}}O\]etc are unable to cause pairing of d-electrons of the central metal atom/ion, thus they usually result in the formation of outer orbit complexes (in case metal ion contains atleast 5 electrons in its d-orbital). Thus,\[{{[Fe{{F}_{6}}]}^{3-}}\]and\[{{[Fe{{({{H}_{2}}O)}_{6}}]}^{2+}}\]are outer orbital octahedral complexes.You need to login to perform this action.
