SUMMARY

Gamma-keto acids do not undergo decarboxylation when subjected to heat, unlike beta-keto acids which can undergo carboxylation. The discussion identifies C as a gamma-keto acid, confirming its classification. The mechanism of decarboxylation in beta-keto acids involves an intermediate that facilitates CO2 removal, which is not present in gamma-keto acids. Therefore, the structural differences between these compounds prevent gamma-keto acids from undergoing similar reactions.

PREREQUISITES
  • Understanding of carboxylation and decarboxylation processes in organic chemistry.
  • Familiarity with the structure and properties of beta-keto and gamma-keto acids.
  • Knowledge of reaction mechanisms involving intermediates in organic reactions.
  • Basic principles of thermal effects on chemical compounds.
NEXT STEPS
  • Research the mechanisms of carboxylation in beta-keto acids.
  • Study the structural characteristics of gamma-keto acids and their reactivity.
  • Explore the role of intermediates in organic reactions, particularly in decarboxylation.
  • Investigate the effects of heat on various organic compounds and their reaction pathways.
USEFUL FOR

Chemistry students, organic chemists, and researchers interested in reaction mechanisms and the behavior of keto acids under thermal conditions.

Choose the carboxylic acid that would not would not undergo decarboxylation when subject to heat.
Relevant Equations
None needed.
Hello all!

I have learned beta-keto acids are able to undergo carboxylation when subjected to heat. Do gamma-keto acids undergo decarboxylation when subjected to heat as well? If not, why?

I identified C as a gamma-keto acid. Do you agree?

Thank you for your help.

Think about the intermediate present in beta keto carboxylates which assists the removal of CO2. Is that possible for your gamma keto compound?
