Write the reaction equation: C2H2 – CH3-CHO – CH3CH2OH – C2H4 – (-CH2-CH2-) n

Let us write down the reaction equations for organic compounds:
C2H2 + H2O = H2C – CHOH (vinyl alcohol) = H3C – CHO – Kucherov’s reaction, acetaldehyde was obtained;
Н3С – СНО + H2 = H3C – CH2OH – additions, ethanol was formed;
Н3С – СН2 – ОН = Н2О + Н2С = СН2 – dehydration, ethylene was obtained;
nH2C = CH2 = (- H2C – CH2 -) n – polymerization reaction, polyethylene was obtained.
The final product of the chain of transformations – polyethylene polymer is used in engineering as a dielectric for the manufacture of cables and pipes, as well as packaging material.
