Which of the following has largest paramagnetism ?A. `[Cr(H_(2)O)_(6)]^(3+)`B. `[Fe(H_(2)O)_(6)]^(2+)`C. `[Cu(H_(2)O)_(6)]^(2+)`D. `[Zn(H_(2)O)_(2)]^(2+)` |

Answer» Correct Answer - B More the number of unpaired electrons , higher is its paramagnetism . `Cr^(3+) : 3d^(3) , Fe^(2+) : 3d^(6) , Cu^(2+) : 3d^(9) , Zn^(2+) : 3d^(10)` `Fe^(2+)` has four unpaired electrons hence it shows highest paramagnetism . |
