Using crystal field theory, choose the correct option regarding the electronic configuration of the central metal atom/ion, and determine the magnetic moment value in the following: [CoF 6 ] 3– , [Co(H 2 O) 6 ] 2+ , [Co(CN) 6 ] 3–
Options
- A[CoF 6 ] 3– : Low spin, 1 unpaired electron, magnetic moment = 1.73 BM
- B[Co(H 2 O) 6 ] 2+ : High spin, 3 unpaired electrons, magnetic moment = 3.87 BM
- C[Co(CN) 6 ] 3– : Low spin, 1 unpaired electron, magnetic moment = 1.73 BM
- D[CoF 6 ] 3– : Low spin, 1 unpaired electron, magnetic moment = 1.73 BM
Correct answer
B. [Co(H 2 O) 6 ] 2+ : High spin, 3 unpaired electrons, magnetic moment = 3.87 BM
Step-by-step solution
Correct Option is : (B) [Co(H 2 O) 6 ] 2+ : High spin, 3 unpaired electrons, magnetic moment = 3.87 BM
