Make the equation for the reactions CaCO3 – CaC2 – C2H2 – CH3 – CH2 – OH – CH3 – CH2 – CI – CH2 = CH2

Let’s compose the equations:
CaCO3 = CaO + CO2 – decomposition reaction, calcium oxide is obtained;
CaO + 3C = CaC2 + CO – the redox reaction occurs at a temperature of 2000 degrees in industrial plants, calcium carbide is released;
CaC2 + 2H2O = Ca (OH) 2 + C2H2 – hydrolysis of calcium carbide, acetylene was formed;
C2H2 + H2O = H2C = CHOH = H3C – CHO – hydration of acetylene;
Н3С – СНО + Н2 = С2Н5 – ОН – hydrogenation, reduction of aldehyde to ethanol occurs;
С2Н5 – ОН + НCl = C2H5CL + H2O – exchange, chloroethane was obtained;
С2Н5Cl + KOH = C2H5 – OH + KCl – exchange, ethanol is released;
С2Н5 – ОН = Н2О + Н2С = СН2 – dehydration of ethylene, ethylene was obtained.
The above reaction equations confirm the relationship between inorganic and organic substances, as well as alkynes and oxygen-containing organic compounds. The final product of the conversion scheme, ethylene, is the basis for the synthesis of polyethylene.
