Among the following series of transition metal ions the one where all meal ions have `3d^2` electronic configuration isA. `Ti^(3+) , V^(2+) , Cr^(3+) , Mn^(4+)`B. `Ti^(+)` , `V^(4+)` , `Cr^(6+)` , `Mn^(7+)`C. `Ti^(+)` , `V^(4+)` , `Cr^(6+)` , `Mn^(7+)`D. `Ti^(2+)` , `V^(3+)` , `Cr^(4+)` , `Mn^(5+)` |

Answer» Correct Answer - D `Ti (3d^(2) 4s^(2)) implies Ti^(+) (3d^(2) 4s^(1)) implies Ti^(2+) (3d^(2)) implies Ti^(3+) (3d^(1))` `V (3d^(3) 4s^(2)) implies V^(2+) (3d^(2)) implies V^(4+) (3d^(1))` `Cr (3d^(5) 4s^(1)) implies Cr^(3+) (3d^(3)) implies Cr^(4+) (3d^(2)) implies Cr^(6+) (3d^(0))` `Mn (3d^(5) 4s^(2)) implies Mn^(4+) (3d^(3)) implies Mn^(5+) (3d^(2)) implies Mn^(7+) (3d^(0))` |
