The spin-only magnetic moments of [ Fe ( NH ₃ )₆ ]³⁺ and [ FeF ₆ ]^ 3- in BM are, respectively,
Options
- A1.73 and 1.73
- B5.92 and 1.73
- C1.73 and 5.92
- D5.92 and 5.92
Correct answer
C. 1.73 and 5.92
Step-by-step solution
array l Fe ³⁺=3 ~d ⁵ array F is W F L so =5.92 While NH ₃ is SFL & pairing of electrons takes place so =1.73
