👉 The term "nontautomerizable" refers to a substance that cannot be made or produced through the reaction of two or more different chemical elements. In other words, it is an element that does not have any known chemical reactions with other elements and therefore cannot be synthesized from reactants. Examples of nontautomerizable substances include: - Helium (He) - Oxygen (O2) - Carbon dioxide (CO2) - Nitrogen gas (N2)
