Explain the difference in magnetic moment values between [Fe(H 2 O) 6 ] 3+ and [Fe(CN) 6 ] 3– based on Crystal Field Splitting theory.

Options

  1. AThe presence of strong-field ligands in[Fe(H 2 O) 6 ] 3+ results in higher spin and magnetic moment.
  2. B[Fe(CN) 6 ] 3– has a higher oxidation state, leading to a greater magnetic moment.
  3. C[Fe(H 2 O) 6 ] 3+ exhibits greater Crystal Field Splitting, enhancing its magnetic moment.
  4. D[Fe(CN) 6 ] 3– experiences weaker crystal field effects, reducing its magnetic moment.

Correct answer

C. [Fe(H 2 O) 6 ] 3+ exhibits greater Crystal Field Splitting, enhancing its magnetic moment.

Step-by-step solution

Correct Option is : (C) [Fe(H 2 O) 6 ] 3+ exhibits greater Crystal Field Splitting, enhancing its magnetic moment.
