Cho sơ đồ chuyển hóa sau:

\(\begin{gathered}
(X) + (Y)\xrightarrow{{(CH3COO)2Mg}}(Z)\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(Z) + NaOH \to (T) + (G) \hfill \\
(T) + NaOH\xrightarrow{{CaO,{t^o}}}C{H_4} + (H)\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(G) + {H_2}\xrightarrow{{Ni,{t^o}}}(I) \hfill \\
(I)\xrightarrow{{H2SO4,{t^o}}}{C_2}{H_4} + H2O\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(X) + NaOH \to (T) + {H_2}O \hfill \\
\hfill \\
\end{gathered} \)
