Make the equation: СН4-СО2-C6H12O6 – C2H5OH-C2H4-C2H5Cl-C4H10

We write down the reaction equations for organic substances:
СН4 + 2О2 = СО2 + 2Н2О – combustion reaction;
6СО2 + 6Н2О = С6Н12О6 – photosynthesis of glucose;
С6Н12О6 = (enzymes) = 2С2Н5ОН + 2СО2 – alcoholic fermentation, ethanol was obtained;
С2Н5ОН = Н2О + С2Н4 – dehydration, ethylene was formed;
С2Н4 + НCl = C2H5Cl – addition, chloroethane was released;
2С2Н5Cl + 2Na = C4H10 + 2NaCl – Wurtz reaction, butane obtained;
These reactions show the connection of alkanes, aldehydes, carbohydrates, alkenes.
