Cho sơ đồ chuyển hóa sau: C3H4O2 + NaOH → X + Y X + H2SO4 loãng → Z + T Biết Y và Z đều có phản ứng tráng gương. Hai chất Y, Z tương ứng là gì?

* Hướng dẫn giải

Đáp án C

\({C_3}{H_4}{O_2}:{\text{ }}HCOOCH{\text{ }} = {\text{ }}C{H_2}\) \(HCOOCH{\text{ }} = {\text{ }}C{H_2} + NaOH\xrightarrow{{}}HCOONa + C{H_3}CHO\) \(\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(X)\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(Y)\) \(HCOONa + {H_2}S{O_4}{\,_{loang}}\xrightarrow{{}}HCOOH + N{a_2}S{O_4}\) \(\,\,\,\,\,\,\,\,(X)\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(Z)\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(T)\)
