👉 The term "nontautomeric" refers to a chemical compound that is composed of different atoms with no repeating units. In other words, it has an atom count of 1 and no repeated groups or subunits. It's similar to a monomeric compound but lacks the properties of a monomer. For example, in a nontautomeric molecule, one atom would be bonded to another atom that is not part of the original molecule. This means there are no double bonds
