Which of the following statements is correct about [Co(H2O)6]2+ complex?
- Electronic configuration = 3d7 → t2g 5 eg 2, no. of unpaired electrons = 3, m = 3.87 B.M.
- Electronic configuration = 3d6 → t2g 4 eg 2, no. of unpaired electrons = 2, m = 2.87 B.M.
- Electronic configuration = 3d7 → t2g 6 eg 1, no. of unpaired electrons = 1, m = 2.87 B.M.
- Electronic configuration = 3d7 = t2g 3 eg 4, no. of unpaired electrons = 3, m = 3.87 B.M.
Answer
(A) Electronic configuration = 3 d 7 → t 2 g 5 e g 2 , no. of unpaired electrons = 3, m = 3.87 B.M.
