Carry out the transformations: ethane-ethylene-ethanol-chloroethane-diethyl ether. Indicate the reaction conditions.

Let’s implement the solution:
C2H6 = C2H4 + H2 – the dehydrogenation reaction occurs when heated in the presence of a catalyst, ethylene is formed;
Н2С = СН2 + НОН = Н3С – СН2 – ОН – hydration reaction, possible when heated in the presence of copper, ethanol is obtained;
C2H5 – OH + HCl = C2H5Cl + H2O – the reaction with hydrogen halide leads to the formation of chloroztane;
С2Н5Cl + KOH = C2H5OH + KCl – exchange reaction, ethanol was obtained;
C2H5 – OH + OH – C2H5 = C2H5 – O- C2H5 + H2O – esterification reaction, occurs when heated in the presence of sulfuric acid as a water-removing agent, diethyl ether is formed.
