Write down the reaction equations: C2H4- C2H5OH- C2H4- CH3CHO- CH3COOH- H2O.

Let’s compose the equations:
С2Н4 + Н2О = С2Н5ОН – ethylene hydration reaction, ethanol was obtained;
С2Н5ОН = Н2О + Н2С = СН2 – ethylene is released;
С2Н4 + Н2О = С2Н5ОН – addition, ethyl alcohol was formed;
С2Н5ОН + CuO = CH3CHO + Cu + H2O – ethanal was obtained;
CH3CHO + Ag2O = CH3 – COOH + 2Ag – acetic acid, silver are released;
CH3 – COOH + NaOH = CH3COONa + H2O – exchange, sodium acetate salt and water were formed.
These reactions show the relationship between organic and inorganic compounds. The reaction products find practical applications, for example, acetic acid as an oxidizing agent, and also in the food industry.
