The product of the reaction between propanoic acid and ethanol is

The product of the reaction between propanoic acid and ethanol is ethylpropanoate. This is because when propanoic acid and ethanol react, they undergo an esterification reaction to form an ester called ethylpropanoate. Esters are organic compounds that are formed from the reaction between an alcohol and a carboxylic acid. In this case, ethanol acts as the alcohol, and propanoic acid acts as the carboxylic acid. The reaction involves the removal of a water molecule, resulting in the formation of the ester. The general reaction can be represented as follows: Carboxylic acid + alcohol → ester + water Propanoic acid + ethanol → ethylpropanoate + water Therefore, the correct answer is ethylpropanoate.
