Question

What is the shape of $Fe(CO{)}_5$ molecule and which of the following d - orbitals involved in hybridization?

• A. Tetrahedral $d_{x^2-y^2}$
• B. Trigonal bipyramidal, $d_{x^2-y^2}$
• C. Trigonal bipyramidal, $d_{z^2}$
• D. Square pyramidal

Answer 1

The correct option is C

Trigonal bipyramidal, $d_{z^2}$

Given the geometry, the $d$ orbital involved is $d_{z^2}$.
