A) \[N{{H}_{3}}<en<C{{N}^{-}}<CO\]
B) \[C{{N}^{-}}<N{{H}_{3}}<CO<en\]
C) \[en<C{{N}^{-}}<N{{H}_{3}}<CO\]
D) \[CO<N{{H}_{3}}<en<C{{N}^{-}}\]
Correct Answer: A
Solution :
Ligands can be arranged in a series in the orders of increasing field strength as given below: \[{{l}^{-}}<B{{r}^{-}}<{{S}^{2-}}<C{{l}^{-}}<NO_{3}^{-}<{{F}^{-}}<O{{H}^{-}}<EtOH<{{C}_{2}}O_{4}^{2-}\]\[<{{H}_{2}}O<NC{{S}^{-}}<EDTA<N{{H}_{3}}<N{{H}_{3}}<en<NO_{2}^{-}<C{{N}^{-}}<CO\] Such a series is termed as spectro chemical series. It is an experimentally determined series based on the absorption of light by complexes with different ligands.You need to login to perform this action.
