The geometry of [Fe(CO)5] is:
Correct answer: D. Bipyramidal
- A. Pyramidal
- B. Square planar
- C. Octahedral
- D. Bipyramidal
Explanation
There are five carbonyl (CO) ligands attached with central atom (Fe), so coordination no is 5. If coordination no is 5 then geometry is trigonal bipyramidal.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
