Which complex of Co^(2+)will have the weakest crystal field splitting

Answer»

`[Co(CN)_(6)]^(4-)`
`[CoCl_(6)]^(4-)`
`[Co(en)_(3)]^(2+)`
`[Co(H_(2)O)_(6)]^(2+)`

Solution :Spectrochemical series
`I^(-) LT Br^(-)lt SCN^(-) lt CL^(-) lt S^(2) lt F^(-)lt OH^(-) lt C_(2)O_(4)^(2-) lt H_(2)Olt NCS^(-) lt EDTA^(4-) lt NH_(3) lt en lt CN^(-) lt CO`
( Strongest)
