Write the equation for the reaction: Ethane – chloroethane – ethanol – ethanal – ethanic acid – sodium acetate

Here are the equations:
H2C = CH2 + Cl2 = H3C – CH2Cl + HCl – halogenation reaction, chloroethane obtained;
Н3С – СН2 – Cl + KOH = H3C – CH2 – OH + KCl – exchange, ethanol was released;
Н3С – СН2 – ОН + CuO = H3C – CHO + Cu + H2O – ethanol oxidation, ethanal was formed;
Н3С – СНО + Ag2O = CH3COOH + 2Ag – oxidation of ethanal, ethanic acid was obtained;
CH3COOH + NaOH = CH3COONa + H2O – exchange, sodium acetate was released.
The final product of the transformation chain is sodium acetate, which is used in the food industry as a preservative.
