Question

[Fe(CN)6] 3– is diamagnetic or paramagnetic?

Answer 1

Answer:

In the [Fe(CN)6]3– has 1 unpaired electron, therefore, it is paramagnetic whereas [Fe(CN)6]3– is diamagnetic because it does not have unpaired electron.

Answer 2

Number of Unpaired Electrons

Explanation:

[Fe(CN)6]3– is complex paramagnetic because it have one unpaired electron.

Paramagnetic character depend upon the number of unpaired electrons on ion.

In the complex [Fe(CN)6 ]3–, the iron is in +3 oxidation state with d5 configuration, so that even after pairing due to strong field of cyanide ligands, one electron will remain unpaired and therefore it is weakly paramagnetic.

Iron is in +3 state and in this complex iron undergoes d2sp3 hybridisation.

Hence, [Fe(CN)6]3- is paramagnetic in the nature.
