Let’s write down the given chain of transformations.
1. C + 2H2 = CH4 (methane is obtained by hydrogenation of carbon).
2. CH4 + Br2 = CH3Br + HBr (bromination of methane leads to the formation of bromomethane, the reaction proceeds by a radical mechanism).
3. 2CH3Br + 2Na = CH3CH2 + 2NaBr (symmetric hydrocarbons are obtained by the Wurtz reaction).
4. CH3CH3 = C2H4 + H2.
5. C2H4 + H2 = CH3CH3 (dehydrogenation and hydrogenation of hydrocarbons is carried out in the presence of a nickel catalyst and at a high temperature).
6. 2CH3CH3 + 7O2 = 4CO2 + 6H2O (carbon dioxide and water are obtained by complete oxidation of ethane).
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
