Arrange following complex ions in increasing order of crystal field splitting energy (Delta_(0)), Cr(Cl)_(6)]^(3-), [Cr(CN)_(3)]^(3-), [Cr(NH_(3))_(6)]^(3+)

Answer»

Solution :The order of increasing `Delta_(0)` VALUE for the complex ions is:
`[CrCl_(6)]^(3-) lt [Cr(NH_(3))_(6)]^(3+) lt [Cr(CN)_(4)]^(3-)`
This is because of increasing order of the `Delta_(0)` VALUESOF the ligands in the spectrochemical series.
