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

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.

Text Solution

Verified by Experts

The correct Answer is:
A
`ln [Fe(CN)_6]^(3-) and [FeF_6]^(3-)` the electronic configration of `Fe^(3+)` is

In both complexes unpaired electrons are present. Thus, both complexes are paramagnetic.
