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 alcohol needed to synthesize the following amide needs to be determined using Fischer esterification reaction.

- 2. What carboxylic acid and alcohol are needed to prepare each ester by Fischer esterification? a) b) c)arrow_forwardEthyl 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). The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0% yield. How many grams would be produced from 8.50 gof butanoic acid and excess ethanol? Express your answer in grams to three significant figures.arrow_forwardWhat carboxylic acid and alcohol are needed to synthesize each ester by Fischer esterifi cation?arrow_forward
