Make up the reaction equation: С2Н6 → С2Н5Вr → С2Н5ОН → СН3СОН → СН3СООН.

Let’s implement the solution:
1. Ethane – bromoethane – ethanol – ethanal – acetic acid.
2. Let’s write down the processes:
C2H6 + Br2 = C2H5Br + HBr – substitutions, bromoethane was obtained;
C2H5Br + KOH = C2H5OH + KBr – exchange, ethanol is released;
С2Н5ОН + CuO = CH3 – COH + Cu + H2O – oxidation of alcohol with copper oxide when heated, ethanal was formed;
СН3СОН + Ag2O = CH3COOH + 2Ag – qualitative reaction for aldehyde, acetic acid was obtained.
3. The solution shows the relationship of hydrocarbons by the example of ethane and oxygen-containing organic compounds – carboxylic acids. The reaction products have practical applications, for example, acetic acid as an oxidizing agent.
