The number of unpaired electrons in the complex ion `[CoF_(6)]^(3-)` isA. 3B. 2C. 4D. 0 |
|
Answer» Correct Answer - C In complex ion `[CoF_(6)]^(3-)`, Co is present in + 3 oxidation state `""_(27)Co=1s^(2),2s^(2)2p^(6),3s^(2)3p^(6)3d^(7),4s^(2)` `Co^(3+)=1s^(2),2s^(2)2p^(6),3s^(2)3p^(6)3d^(6)` Therefore, the number of unpaired electrons in 3d subshell of `[CoF_(6)]^(3-)` is 4. |
