Which of the following ions has the maximum magnetic moment in aqueous solution ?A. `Mn^(2+)`B. `Fe^(2+)`C. `Co^(2+)`D. `Cr^(2+)` |
|
Answer» Correct Answer - 1 `(1)` Valence shell electron configuration of `Mn^(2+)` is `3d^(5)`, therefore, has the maximum number of unparied electrons equal to 5 and , therefore, has maxium magnetic moment. `(2)` Valence shell electron configuratino of `Fe^(2+)` is `3d^(6)`, therefore, has the maximum number of unpaired electrons equal to 4. `(3)` Valence shell electron configuration of `Co^(2+)` is `3d^(7)`, therefore, has the maximum number of unpaired electrons equal to 3. `(4)` Valence shell electron configuration of `Cr^(2+)` is `3d^(4)`, therefore, has the maximum number of unparied electrons equal to 4. |
