Given the following data about the absorption maxium of several complex ions what is the order of `Delta_(0)` for these ions? .
`{:(Compound,,lambda_(max),,),(I.[CrCI_(6)]^(3-),,758,,),(II.[Cr(NH_(3))_(6)]^(3+),,465,,),(III.[Cr(H_(2)O)_(6)]^(3+),,694,,):}`
(a) `Delta_(0)ltdelta_(0)(II)ltDelta_(0)(III)`
(b) `delta_(0)(II)ltDelta_(0)(III)ltDelta_(0)(III)`
(c) `Delta(0)ltdelta_(0)(III)ltDelta_(0)(II)`
(d) `Delta_(0)(III)ltDelta_(0)(II)ltDelta_(0)(I)` .

Text Solution

Verified by Experts

The correct Answer is:
c
The higher is the value of `Delta_(0)` lower is the value of `lambda` max and vice varsa and hence answer is ©
