Question

Viết pt thể hiện dãy chuyển hoá sau:

\(Etanol\xrightarrow[]{-H_2O}X_1\xrightarrow[80^\circ C]{+H_2O\text{ / }Hg^{2+}}X_2\xrightarrow[]{-H_2O}X_3\)

\(X_2\xrightarrow[t^\circ]{Cu}X_4\xrightarrow[t^\circ]{+O_2,Cu}X_5\)

Answer 1

\(C_2H_5OH\xrightarrow[H_2SO_4\left(\text{đ}\right)]{170^{\circ}C}C_2H_4^{\left[X_1\right]}+H_2O\) 

\(3C_2H_4+2KMnO_4+4H_2O\xrightarrow[]{t^\circ}3C_2H_4\left(OH\right)_2^{\left[X_2\right]}+2KOH+2MnO_2\downarrow\)

\(C_2H_4\left(OH\right)_2\xrightarrow[H_2SO_4\left(\text{đ}\right)]{170^\circ C}CH_3CHO^{\left[X_3\right]}+H_2O\)

\(2C_2H_4\left(OH\right)_2+O_2\xrightarrow[t^{\circ}]{Cu}2HOCH_2CHO^{\left[X_4\right]}+2H_2O\)

\(2HOCH_2CHO+O_2\xrightarrow[t^\circ]{Cu}2\left(CHO\right)_2^{\left[X_5\right]}+2H_2O\)
