Study Notes
Decomposition Reactions by Heating
- The Soda lime method decomposes organic compounds RO into RH and Na2CO3 via heat.This method is used to determine the α stability of RO.
Decomposition of Gemdicarboxylic Acids
- Gemdicarboxylic acids, such as CH2(COOH)2, undergo decomposition when heated, resulting in the formation of CH2=CHCOOH.
- This reaction involves the breakdown of the gemdicarboxylic acid into a simpler compound.
β-Ketoacid Decomposition
- β-Ketoacids, characterized by the R-C(=O)-CH2-COOH structure, decompose into R-C(=CH2)-CH3 when heated.
- The stability of the enol formed during this reaction is a crucial factor in the decomposition process.
β, γ-Unsaturated Acid Decomposition
- β, γ-Unsaturated acids, such as CH2=CH-CH2-C(=O)OH, undergo decomposition when heated, resulting in the formation of CH2=CH-CH2.
- This reaction involves the breakdown of the unsaturated acid into a simpler compound.
