The correct structure of `Fe(CO)_(5)` is (Z = 26 for Fe)

A

octahedral

B

square planar

C

trigonal bipyramidal

D

square pyramidal

Text Solution

Verified by Experts

The correct Answer is:
C

In `Fe(CO)_(5),` the Fe-atom is in `dsp^(3)` hybridised state, therefore the shape of molecule is trigonal bipyramidal The hybridisation is as follows:
`""_(26)Fe=1s^(2),2s^(2)2p^(6),3s^(2)3p^(6)3d^(6),4s^(2)4p^(0)`
In presence of strong field ligand (CO), the electrons of 4s are pushed in 3d orbital and get paired up.
In `Fe(CO)_(5),` the Fe-atom is
