Chemistry Question on Aldehydes, Ketones and Carboxylic Acids
Self condensation of two moles of ethyl acetate in presence of sodium ethoxide yields:
A
ethyl butyrate
B
acetoacetic ester
C
methyl acetoacetate
D
ethyl propionate
Answer
acetoacetic ester
Explanation
Solution
The condensation of two moles of ethyl acetate in the presence of sodium ethoxide results in the formation of acetoacetic ester. This reaction is known as a Claisen condensation and involves the combination of two molecules of ethyl acetate to produce acetoacetic ester.
Reaction: 2CH₃COOC₂H₅ + 2NaOC₂H₅ → CH₃COCH₂COOC₂H₅ + 2C₂H₅OH
So, the correct option is (B): acetoacetic ester
