Write the reaction equations: Ethene – ethanol – ethanal – acetic acid – methyl ester of acetic acid

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

С2Н4 – С2Н5ОН – С2Н4О – СН3СООН – СН3СОО – СН3

Н2С = СН2 + Н2О = СН3 – СН2ОН – hydration occurs in water vapor, ethanol is released;

С2Н5ОН + CuO = CH3 – COH + Cu + H2O – oxidation of aldehyde with copper oxide on heating, ethanal was obtained;
CH3 – СОН + Ag2O = CH3COOH + 2Ag – acetic acid is released during the reaction of a silver mirror, aldehyde is oxidized by an ammonia solution of silver oxide when heated;
CH3COOH + CH3OH = CH3COO – CH3 + H2O – esterification proceeds when heated in the presence of H2SO4, as a dehydrating agent, the methyl ester of acetic acid is formed.
The solution confirms the connection of unsaturated hydrocarbons by the example of ethene with oxygen-containing substances. The end product of the transformation chain, ethyl acetate, is used in the food industry as a flavoring agent.
