Definition - What does Isomerization mean?

Isomerization is the process in which one molecule gets transformed into another molecule that has absolutely the same atoms which are arranged in a different way. Several isomers are roughly equal in the bond energy and exist in equal amounts. If two isomers interconvert approximately freely it means that the energy barriers between the two isomers are not high. Isomerization of the straight-chained hydrocarbon to its analogous branched chain isomer is an essential step in the manufacture of gasoline.

Petropedia explains Isomerization

Intramolecularly occurring Isomerization is given due consideration as a rearrangement reaction. Isomerization transforms the straight-chained hydrocarbons into branched chain hydrocarbons. It spontaneously takes place under some conditions and in some molecules. The difference between the energies of two isomers is known as Isomerization energy. Isomers are compounds with the same molecular formula but the arrangement of the atoms is different. A compound can display various types of isomerism. Cyclic compounds are formed in the cycloisomerization. When dynamic equilibrium is made between two isomers, it is referred to as valence tautomerism.
