Which of the following options explains [Fe(H 2 O) 6 ] 3+ is strongly paramagnetic whereas [Fe(CN) 6 ] 3– is weakly paramagnetic?
Options
- ABoth [Fe(H 2 O) 6 ] 3+ and [Fe(CN) 6 ] 3– have the same degree of paramagnetism, so there is no difference in
- B[Fe(H 2 O) 6 ] 3+ has a higher oxidation state, resulting in stronger paramagnetism compared to [Fe(CN) 6 ] 3–
- CIn the case of [Fe(CN) 6 ] 3– , CN - leads to an inner orbital complex with one unpaired electron, but for [Fe
- D[Fe(H 2 O) 6 ] 3+ has a lower coordination number, leading to stronger paramagnetism compared to [Fe(CN) 6 ] 3
Correct answer
C. In the case of [Fe(CN) 6 ] 3– , CN - leads to an inner orbital complex with one unpaired electron, but for [Fe
Step-by-step solution
Correct Option is : (C) In the case of [Fe(CN) 6 ] 3– , CN - leads to an inner orbital complex with one unpaired electron, but for [Fe(H 2 O) 6 ] 3+ ,H 2 O leads to form an outer orbital complex with five unpaired electrons.
