For the following reactions, the metal complexes X and Y are (i) $\mathrm{Ni}(\mathrm{s}) \xrightarrow[1 \mathrm{atm} / 25^{\circ} \mathrm{C}]{\mathrm{CO}(\mathrm{g})} \mathrm{X}$ (ii) $\mathrm{FeCl}_{2} \xrightarrow{2 \mathrm{NaC}_{5} \mathrm{H}_{5}} \mathrm{Y}$
(a)$\mathrm{X}=\mathrm{Ni}(\mathrm{CO})_{4} ; \mathrm{Y}=\mathrm{Fe}\left(\eta^{5}-\mathrm{C}_{5} \mathrm{H}_{5}\right)_{2}$
(b)$\mathrm{X}=\mathrm{Ni}(\mathrm{CO})_{4} ; \mathrm{Y}=\mathrm{Fe}\left(\eta^{1}-\mathrm{C}_{5} \mathrm{H}_{5}\right)_{2}$
(c)$\mathrm{X}=\mathrm{Ni}(\mathrm{CO})_{5} ; \mathrm{Y}=\mathrm{Fe}\left(\eta^{5}-\mathrm{C}_{5} \mathrm{H}_{5}\right)_{2}$
(d)$\mathrm{X}=\mathrm{Ni}(\mathrm{CO})_{6} ; \mathrm{Y}=\mathrm{Fe}\left(\eta^{1}-\mathrm{C}_{5} \mathrm{H}_{5}\right)_{2}$
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
Ni + 4CO → Ni(CO)₄ (Mond); FeCl₂ + 2NaC₅H₅ → ferrocene Fe(η⁵-C₅H₅)₂ (a).
