Question

Hybridization of iron in $Fe(CO{)}_5$ is

• A. $ds{p}^3$
• B. $s{p}^{3}d$
• C. $d^{2}s{p}^3$
• D. $s{p}^3{d}^2$

Answer 1

Answer: (A)

$ds{p}^3$

Since $Fe$ has $5$ carbonyl around it, it has trigonal bi pyramidal geometry and shape and has hybridization- $ds{p}^3$. The splitting of various orbitals of $d$ subshells to different energy is based on the repulsions experienced because of the approaching ligand as, $CO$ is a neutral ligand

Option A is correct
