Isomerism

Isomerism is an important phenomenon in chemistry and biochemistry where different molecules have the same chemical composition, but different arrangements at the molecular level. Isomers are structurally different molecules that have the same molecular formula and the same types of atoms. Isomerism is important because it explains the different physical and chemical properties between different molecules. It is also used to help with mass spectrometry and the identification of unknown chemical compounds in the laboratory. Additionally, isomerism plays an important role in the production of drugs, coatings and plastics and can be used to create materials with desired chemical and physical properties.
