Write the equation for the reactions Glucose-Ethanol-Ethen-Ethane-CO2. Specify the conditions for the reaction.

Let’s execute the solution:

С6Н12О6 – С2Н5ОН – С2Н4 – С2Н6 – СО2

С6Н12О6 = 2С2Н5ОН + 2СО2 – ethanol was obtained in the process of alcoholic fermentation of glucose;
С2Н5ОН = Н2О + Н2С = СН2 – ethanol dehydration occurs when heated on a copper catalyst, ethene is formed;
H2C = CH2 + H2 = CH3 – CH3 – hydrogenation, ethane is released;
С2Н6 + 7О2 = 4СО2 + 6Н2О + Q – combustion of ethane, carbon monoxide (4) is formed, heat, water.
The solution shows the relationship between organic and inorganic substances using the example of glucose and carbon dioxide. Reactions have a practical purpose, for example, ethane is part of natural gas, used as a fuel.
