Isomerization is a chemical process in which a molecule is converted into an isomer, a version of the molecule with the same molecular formula but a different structural formula. This process is crucial in various fields, including organic chemistry, biochemistry, and industrial chemistry. Isomerization can occur through different mechanisms, such as rotation around single bonds, rearrangement of atoms, or the breaking and reforming of chemical bonds.

In organic chemistry, isomerization is often used to synthesize complex molecules from simpler precursors. For example, the isomerization of alkenes can lead to the formation of different isomers, which can have varying physical and chemical properties. This process is also important in the synthesis of pharmaceuticals, where specific isomers may exhibit different biological activities.

In biochemistry, isomerization plays a role in metabolic pathways. Enzymes can catalyze the isomerization of molecules, facilitating reactions that would otherwise be thermodynamically unfavorable. This is particularly important in the metabolism of carbohydrates and amino acids.

Industrially, isomerization is used in the production of various chemicals and fuels. For instance, the isomerization of n-butane to isobutane is a key step in the production of gasoline. This process increases the octane rating of the fuel, making it more suitable for use in internal combustion engines.

Isomerization can be reversible or irreversible, depending on the conditions and the specific reaction. Reversible isomerization allows for the interconversion of isomers, while irreversible isomerization leads to the formation of a stable isomer. The study of isomerization provides insights into the structure and reactivity of molecules, contributing to the development of new materials and pharmaceuticals.
