Interpretation:
Whether the product obtained by the bromination of optically active (R)-2-phenylpropanoic acid under Hell-Volhard-Zelinski conditions is optically active or racemic is to be explained.
Concept introduction:
Hell-Volhard-Zelinski reaction takes place through the formation of an acid bromide enol intermediate. If the chiral carbon of the optically active

- 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) Given 8.50 g of butanoic acid and excess ethanol, how many grams of ethyl butyrate would be synthesized, assuming a complete 100%yield? Express your answer in grams to three significant figures.arrow_forwardEthyl butyrate, CH3CH2CH2CO2CH2CH3, is an artificial fruit flavor commonly used in the food industry for such flavors as orange and pineapple.
