Substituents
Substituents in organic chemistry refer to functional groups or atoms that replace hydrogen atoms in a molecule. These substituents can significantly influence the chemical properties, reactivity, and physical characteristics of the organic compounds they comprise. Understanding the nature and effects of substituents is essential in predicting and explaining the behavior …
