The crystal field-splitting for Cr^(3+)ion in octahedral field changes for I^("ϴ"), H_(2)O, NH_(2), CN^("ϴ")and the increasing order is :-

Answer»

`I^("ϴ") lt H_(2)O lt NH_(3) lt CN^("ϴ")`
`CN^("ϴ") lt I^(-) lt H_(2)O lt NH_(3)`
`CN^("ϴ") lt NH_(3) lt H_(2)O lt I^("ϴ")`
`NH_(3) lt H_(2)O lt I^("ϴ") lt CN^("ϴ")`
