Chemistry Question on Chemical bonding and molecular structure

Shape  of  Fe(CO)5 is:\text {Shape \ of }\ Fe(CO)_5\ \text {is:}

A

Octahedral\text {Octahedral}

B

Square  planar\text {Square \ planar}

C

Trigonal bipyramidal\text {Trigonal\ bipyramidal}

D

Square pyramidal\text {Square\ pyramidal}

Answer

Trigonal bipyramidal\text {Trigonal\ bipyramidal}

Explanation

Solution

In the trigonal bipyramidal geometry, the central iron atom is surrounded by five ligands (carbon monoxide molecules). Three of these CO\text {CO} ligands are arranged in a trigonal plane, while the other two are located above and below the plane, making the shape trigonal bipyramidal.

So, the correct option is (C): Trigonal bipyramidal
