Which statement is true for ferrocene?
- AAll $Fe-C$ are of equal length
- BIt has sandwich type structure
- CIt was the first discovered organometallic compound
- ✓All of these
✓
Answer
Correct option: D.
All of these
d
Ferrocene was the first organometallic compound discovered by $G$. Wilkinson in $1957$. The bonding in these aromatic sandwich type structure is better considered as $\pi -$ bonding involving the lateral overlap of $d_{xz}$ and $d_{yz}$ orbitals on $Fe$ with the delocalized $\pi -$ aromatic orbital from each cylopentadienyl ring. All the five $C-$ atoms are equidistant from $Fe$. Hence all of these statements are true.
