Which of the following is true for the species 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 these |
| Answer» `Cr^(2+)` is reducing as its configuration changes from `d^(4)` to `d^(3)` the latter having a half-filled `t_(2g)^(3)` energy level to 3d orbitals in oxtahedral crystal field spliting. On the other hand, the change from `Mn^(3+)` to `Mn^(2+)` results in the half-filled `(d^(5))` configuration which has extra stability. Therefore, (C) option is correct. | |
