In an advanced synthetic chemistry experiment, a researcher prepares a compound, ZY-7, by reacting a ketone (C5H10O) with hydroxylamine (NH2OH), followed by heating in the presence of an acid catalyst. The resulting compound, ZY-7, is then treated with a solution of sodium nitrite (NaNO2) and hydrochloric acid (HCl) at low temperature. Identify the class of compound that ZY-7 most likely belongs to after this series of reactions."

Alkenes can be converted to alcohols by reaction with mercuric acetate to form a ß-hydroxyalkylmercury(II) acetate compound, a reaction called oxymercuration. Subsequent reduction with NaBH reduces the C-Hg bond to a C-H bond, forming the alkyl alcohol, a reaction called demercuration. Draw the structure of the Hg-containing compound and the final alcohol product formed in the reaction sequence.

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.
