Draw up the conversion schemes with which you can get C2H5-O-C2H5 from CH4. Write down the equations of the reactions underlying them.
Here is the scheme of transformations:
CH4 – CH3Cl – C2H6 – C2H5Cl – C2H5 – OH – C2H5 – O – C2H5
Let’s write the equations:
CH4 + Cl2 = CH3Cl + HCl – substitution reaction, methane chloride is released;
2CH3Cl + 2Na = C2H6 + 2NaCl – Wurtz reaction, ethane obtained;
C2H6 + Cl2 = C2H5Cl + HCl – substitution, ethane chloride was formed;
С2Н5Cl + KOH = C2H5 – OH + KCl – exchange, ethanol was released;
С2Н5ОН + С2Н5ОН = С2Н5 – О – С2Н5 + Н2О – esterification occurs in the presence of sulfuric acid as a dehydrating agent, diethyl ether is obtained.
The end product of the ether chain of transformations – diethyl ether is used in medicine for disinfection before giving an injection. The reactions show a bond between alkanes and oxygenated organic compounds.
