The correct statement about the magnetic...

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

A

Both are paramagnetic

B

Only `[Fe(CN)_6]^(3-)` is paramagnetic

C

Only `[FeF_6]^(3-)` is paramagnetic

D

both are diamagnetic

Text Solution

Verified by Experts

The correct Answer is:
A

`F^-` F is a weak field ligand which can not cause pairing of electrons of 3d orbital of Fe . So `[FeF_6]^(3-)` is paramagnetic due to 5 unpaired electrons. Thus, due to 2 unpaired electrons, it is paramagnetic.
