    Among the following species the one which causes the highest \[CFSE,{{\Delta }_{o}}\] as a ligand is:

    A) \[C{{N}^{-}}\]            

    B) \[~N{{H}_{3}}\]

    C) \[{{F}^{-}}\]                           

    D) CO

    Correct Answer: D

    Solution :

    [d] Following is the order of increasing value of \[{{\Delta }_{o}}\] for the ligands. \[{{I}^{-}}<B{{r}^{-}}<C{{l}^{-}}<{{F}^{-}}<{{H}_{2}}O<Py=N{{H}_{3}}<en<\] \[N{{O}_{2}}^{-}<<C{{N}^{-}}<CO\]
