The hybridisation of Fe is K 3 [ Fe ( CN ) 6 ] is
Options
- Asp 3
- Bdsp 3
- Csp 3 d 2
- Dd 2 sp 3
Correct answer
D. d 2 sp 3
Step-by-step solution
Electronic configuration of Fe = [ Ar ] 4   s 2 3   d 6 Fe 2 + = [ Ar ] 3 d 6 CN - are strong field ligands d 2 sp 3 hybridisation ∵   CN - is a strong ligand and from six coordinate bonds with Fe 3 + . Thus Fe show d 2 sp 3 hybridisation in K 3 Fe ( CN ) 6 .
