The product formed when 2,3-butanedione is treated with 2 equivalents of H 2 in the presence of a palladium catalyst should be determined. Concept Introduction: In a reduction of an organic molecule, either the number of C-O bonds decreases or number of C-H bonds increases. So when a ketone is reduced by H 2 in the presence of Pd catalyst, C=O double bond is reduced to C-O single bond and H 2 is added across this C=O double bond forming a secondary alcohol.

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). 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.
