In aqueous solution `Cr^(2+)` is stronger reducing agent than `Fe^(2+)`. This is becauseA. `Cr^(2+)` ion is more stable than `Fe^(2+)`B. `Cr^(3+)` ion with `d^(3)` configuraion has favourable crystal field stabilisation energyC. `Cr^(3+)` has half-filled configuration and hence more stableD. `Fe^(3+)` in aqueous solution more stable than `Cr^(3+)` |
|
Answer» Correct Answer - B `Cr^(3+)` ions with `d^(3)(t_(2g)^(3))` configuration has favourable crystal field stabilisation atomic energy. |
