The
Concept Introduction:
When carboxylic acid (RCOOH) is treated with an alcohol (R'OH) in an acidic medium, an ester (RCOOR') formation can be observed. This process is known as the Fischer esterification.
In this esterification process, the OR' group of an alcohol replaces the OH group of the starting carboxylic acid.
General reaction is represented as follows:
(b)
Interpretation:
The carboxylic acid and alcoholneeded to synthesize the given ester by Fischer esterification needs to be determined.

- Ethyl butyrate, CH3CH2CH2CO2CH2CH3, 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+): CH3CH2CH2CO2H(l)+CH2CH3OH(l)H+⟶CH3CH2CH2CO2CH2CH3(l)+H2O(l) a) Given 7.70 g of butanoic acid and excess ethanol, how many grams of ethyl butyrate would be synthesized, assuming a complete 100% yield? b) A chemist ran the reaction and obtained 5.25 g of ethyl butyrate. What was the percent yield? c) The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0% yield. How many grams would be produced from 7.70 g of butanoic acid and excess ethanol?arrow_forwardEthyl butyrate, CH3CH2CH2CO2CH2CH3, is an artificial fruit flavor commonly used in the food industry for such flavors as orange and pineapple.
