Question

Ferrocene is stable since $\pi$-electrons in cyclopentadienyl ion are delocalized.

• A. True
• B. False

Answer 1

The correct option is A True

The given statement is True.
Ferrocene is stable since $\pi -$ electrons in cyclopentadienyl ion are delocalized. Ferrocene is $C{p}_{2}Fe$, where Cp represents cyclopentadienyl anion which is aromatic as it contains $4n+2$ $\pi$ electrons (6 $\pi$ electrons) which are delocalised, the anion is cyclic and planar.
