Verified step by step guidance1
Understand the concept of decarboxylation: Decarboxylation is a chemical reaction that involves the removal of a carboxyl group from a molecule, releasing carbon dioxide (CO₂). This process typically results in the breaking of a carbon-carbon bond.
Identify the key characteristic of decarboxylation: In organic chemistry, decarboxylation is characterized by the breaking of a carbon-carbon bond, specifically between the carbon of the carboxyl group and the rest of the molecule.
Compare with other reactions: Hydrolysis involves breaking bonds with water, typically not carbon-carbon bonds. Hydrogenation adds hydrogen to unsaturated bonds, and esterification forms an ester from an acid and alcohol, neither of which primarily involves breaking carbon-carbon bonds.
Recognize the context of the question: The question asks for a reaction characterized by breaking a carbon-carbon bond, which aligns with the process of decarboxylation.
Conclude the analysis: Based on the characteristics of decarboxylation, it is the correct answer as it involves the breaking of a carbon-carbon bond, unlike the other reactions listed.
