Draw up an equation of reactions that can be used to carry out the following transformations: CH3CHO- C2H5OH- CH3CH2Br- C2H4 ↓ CH3COOH Give names to all compounds

Let us write down the equations for the transformation chain:
СН3СНО + Н2 = С2Н5ОН – the reaction of ethanal hydrogenation with hydrogen, ethanol is released;
C2H5 – OH + KBr = C2H5Br + KOH – exchange, bromoethane was obtained;
C2H5Br + KOH = C2H5 – OH + KBr – exchange, ethanol was formed;
С2Н5ОН = С2Н4 + Н2О – dehydration reaction, ethylene was obtained;
C2H4 + HCl = C2H5Cl – addition, ethane chloride was formed;
С2Н5Cl + KOH = C2H5 – OH + KCl – exchange, ethanol is released;
С2Н5ОН + CuO = CH3CHO + Cu + H2O – qualitative reaction to ethanol, alcohol is oxidized to ethanal;
CH3CHO + Ag2O = CH3 – COOH + 2Ag – oxidation of aldehyde occurs when heated with copper oxide, acetic acid and silver are released.
