Write the reactions of the transformation chain C2H5Cl – C2H5OH – C2H5CO-O-C2H5 – C2H5COOH

Let’s carry out the solution of the transformation chain for organic substances:

Ethane chloride – ethyl alcohol – propionoethyl ether – propionic acid

C2H5Cl + KOH = C2H5OH + KCl – exchange, ethyl alcohol was formed;
С2Н5ОН + СН3 – СН2 – СООН = С2Н5 – СОО – С2Н5 + Н2О – esterification, propionoethyl ether is isolated;
С2Н5 – СОО – С2Н5 + Н2О = С2Н5СООН + С2Н5ОН – ether hydrolysis, propionic acid was obtained.
The solution shows the connection between representatives of the classes of oxygen-containing organic compounds using the example of ethyl alcohol, propionic acid, and ester.
