    Among the ligands \[N{{H}_{3}}\], en, \[C{{N}^{-}}\] and CO, the correct order of their increasing field strength is

    A) CO <\[N{{H}_{3}}\]<en<\[C{{N}^{-}}\]

    B) \[N{{H}_{3}}\]<en<\[C{{N}^{-}}\]<CO

    C) \[C{{N}^{-}}\]<\[N{{H}_{3}}\]<CO<en

    D) en <\[C{{N}^{-}}\]<\[N{{H}_{3}}\]<CO

    Correct Answer: B

    Solution :

    [b] Based on spectrochemical series, ligands arranged in increasing order of crystal field strength are as \[N{{H}_{3}}<en<C{{N}^{-}}<CO\]
