Which of the following is true for the speical having `3d^(4)` configuration ?A. `Cr^(2+)` is reducing in nature.B. `Mn^(3+)` is oxidising in nature.C. Both (A) and (B)D. None of those |
| Answer» `Cr^(2+)` is reducing as its configuration changes from `d^(4)` to `3d^(4)`, the latter having a halg-filled t^(3)`_(2g)` energy level of `3d` orbitals in octahedral crystal field soliting . On the other hand , the change from `Mn^(3+)`result in the half-filled `(d^(5))` configuration which has extra stability. Therefore(C) is correct. | |
