n. a chemical reaction in which the structure of a molecule is altered without changing its molecular formula. Often involves the migration of atoms or groups within the molecule.
The acid catalyzed the rearrangement of the double bond.
During the heating process, the compound underwent a structural rearrangement that increased its stability.
The study focused on the thermal rearrangement of the starting material, which eventually led to the formation of a more complex and biologically active product.
