Which one of the following is wrongly matched?
A.[Cu(NH3)4]2+ — Square planar
B.[Ni(CO)4] — Neutral ligand
C.[Fe(CN)6]3– — sp3 d2✓ Correct
D.[Co(en)3]3+ — Follows EAN rule
Explanation
As [Fe(CN)6]3– is an inner orbital octahedral complex therefore its hybridization will be d2sp3 instead of sp3d2 as pairing will take place because of the presence of a strong ligand. Therefore the correct answer will be (c).
