Carry out the following transformations: C2H6 – C2H4 -C2H5OH-C2H4

To solve, we write down the chain of transformations for organic substances:

Ethane – ethene – ethanol – ethene

CH3 – CH3 = H2 + H2C = CH2 – dehydrogenation, ethene obtained;
Н2С = СН2 + Н2О = СН3 – СН2ОН – hydration, ethanol was formed;
С2Н5ОН = Н2С = СН2 + Н2О – dehydration, ethene (ethylene) is released.
The solution confirms the relationship between hydrocarbons and oxygen-containing organic substances by the example of ethane and ethanol. The reaction products find use, for example, ethylene, which is the basis for the production of polyethylene.
