(a)
Interpretation:
Whether the given statement is true or false.
Keto and enol tautomers are constitutional isomers.
Concept Introduction:
A carbonyl compound that has a hydrogen on an a-carbon changes its form to enol through resonance. Both the form stays in equilibrium.
Constitutional isomers are those where the molecular formula for both the compound is same but the bond connectivity differs.
(b)
Interpretation:
Whether the given statement is true or false.
For a pair of keto-enol tautomers, the keto form generally predominates.
Concept Introduction:
A carbonyl compound that has a hydrogen on an a-carbon changes its form to enol through resonance. Both the form stays in equilibrium.
Constitutional isomers are those where the molecular formula for both the compound is same but the bond connectivity differs.

- 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) Part A Given 7.30 gg 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. Part B A chemist ran the reaction and obtained 5.95 gg of ethyl butyrate. What was the percent yield? Express your answer as a percent to three significant figures. Part C The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0%% yield.
