Question
Complete the following statements from the options a-e provided. write the letter of the best correct response in the box provided. a. The reaction of ethyl acetoacetate (C_6H_10O_3; structure in reference) with aqueous NaOH followed by treatment with ethyl iodide A would give ethylacetoacetate with an ethyl group attached on the carbon between the two C = O groups. B would give ethylacetoacetate with an ethyl group attached on the methyl carbon adjacent to the ketone C = O. C would give butanoic acid. D would give ethyl butanoate. b. The reaction of acetaldehyde (ethanol) with excess methanol in acidic solution would give a product that would expected to have A one oxygen and one double bond. B two oxygens and no double bond. C two oxygens and one double bond. D None of the above provide a correct response. e. The reaction of cyclopent-2-eneone with Li(CH_3)_2.cu would give as the major organic product after workup a compound with A seven carbons and one double bonExplanation / Answer
A. A, example for alkylation of 1,3-dicarbonyl compounds
B. B, example for acetal formation
C C, example for alkylation at beta carbon of unsaturated carbonyl compounds using Gilmanns reagent
D. B, since LiAlH4 is strong reducing agent it reduces the both ketone and ester to alcohols
