When butanoic acid and 18 O -labeled methanol react under acidic conditions, the compounds formed at equilibrium has to be labeled. Concept introduction: The reaction between carboxylic acid and an alcohol forms an ester. This type of reaction is known as esterification reaction. Water is formed as by-product in the esterification reaction. Under acidic conditions, the esterification reaction is reversible in nature.

Ethyl butyrate, CH3CH2CH2CO2CH2CH3CH3CH2CH2CO2CH2CH3, is an artificial fruit flavor commonly used in the food industry for such flavors as orange and pineapple. Its fragrance and taste are often associated with fresh orange juice, and thus it is most commonly used as orange flavoring. It can be produced by the reaction of butanoic acid with ethanol in the presence of an acid catalyst (H+H+): CH3CH2CH2CO2H(l)+CH2CH3OH(l)H+⟶CH3CH2CH2CO2CH2CH3(l)+H2O(l)CH3CH2CH2CO2H(l)+CH2CH3OH(l)⟶H+CH3CH2CH2CO2CH2CH3(l)+H2O(l) A chemist ran the reaction and obtained 5.40 g of ethyl butyrate. What was the percent yield, The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0% yield.
