Verified step by step guidance

1. Identify the β-keto ester structure in each given image. A β-keto ester typically has a keto group (C=O) at the beta position relative to the ester group (COOR).
2. Understand the process of hydrolysis: In the presence of an acid or base, the ester group (COOR) is converted into a carboxylic acid (COOH).
3. Recognize the decarboxylation step: Upon heating, the carboxylic acid group (COOH) adjacent to a keto group (C=O) will lose carbon dioxide (CO2), resulting in the formation of a ketone.
4. Apply these transformations to each β-keto ester: For each structure, first perform hydrolysis to convert the ester to a carboxylic acid, then apply decarboxylation to form the corresponding ketone.
5. Draw the resulting ketone structures for each β-keto ester after completing the hydrolysis and decarboxylation steps.

Key Concepts

β-Keto Esters

β-keto esters are organic compounds that contain both a ketone and an ester functional group, with the carbonyl group of the ketone positioned at the β-carbon relative to the ester group. They are important intermediates in organic synthesis and can undergo various reactions, including hydrolysis and decarboxylation, leading to the formation of ketones.

Hydrolysis

Hydrolysis is a chemical reaction involving the breakdown of a compound by water. In the context of β-keto esters, hydrolysis typically refers to the reaction where the ester group is converted into a carboxylic acid and an alcohol, which can subsequently lead to the formation of ketones when combined with decarboxylation.

Decarboxylation

Decarboxylation is the process of removing a carboxyl group (-COOH) from a molecule, releasing carbon dioxide (CO2). In the case of β-keto esters, decarboxylation occurs after hydrolysis, resulting in the formation of a ketone. This reaction is significant in organic synthesis as it helps in the formation of more complex molecules from simpler precursors.
