The correct statement about the magnetic properties of `[Fe(CN)_(6)]^(3-) and [FeF_(6)]^(3-) ` is : (Z=26)

Options

A. both are paramagnetic
B. both are diamagnetic
C. `[Fe(CN)_6]^(3-)` is diamagnetic `[FeF_6]^(3-)` is paramagnetic .
D. `[Fe(CN)_6]^(3-)` is paramagnetic , `[FeF_6]^(3-)` is diamagnetic

Answer

A

Explanation

Both are paramagnetic , the only difference is that `CN^-` is a strong field ligand whereas `F^-` is a weak field ligand.
