Write the reaction equation: CH3 – CH3 -> CH2 = CH2 -> CH3 – CH2OH -> CH3 – CH2ONa

Let us write down the reaction equations for organic substances:
Н3С – СН3 = Н2 + Н2С = СН2 – dehydrogenation reaction, ethylene was obtained;
Н2С = СН2 + Н2О = Н3С – СН2 – ОН – hydration, ethanol was formed;
2Н3С – СН2 – ОН + 2Na = 2H3C – CH2 – ONa + H2 – substitutions, sodium ethylate is released.
These reactions show the bond between alkanes, alkenes, alcohols. Reaction products have practical applications. Ethane and ethanol are used as fuel, and ethylene is used in the production of alcohols and polyethylene.
