The electrophile $\mathrm{Ph_3C}$ reacts with $\mathrm{[(\eta 5\text{-}C_5H_5)Fe(CO)_2(CDMe_2)]^{+}}$ to give a product A. The product A is formed because
(a)Fe is oxidized
(b)alkyl is susbtituted with $\mathrm{Ph_3C}$
(c)Fe-Ph bond is formed
(d)Alkyl is converted to alkene
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
Ph₃C⁺ abstracts the β-hydride (here D-free H) from the isopropyl group, giving the cationic η²-propene complex — alkyl converted to alkene (d).
