Organic reactions are processes in which organic compounds undergo chemical transformations. These reactions are fundamental to the field of Organic Chemistry and involve the breaking and forming of chemical bonds, leading to the creation of new substances. Common types of organic reactions include substitution, addition, and elimination reactions, each with unique mechanisms and applications. Understanding organic reactions is crucial for various fields, including pharmaceuticals, where they are used to synthesize new drugs. The study of these reactions helps chemists predict the behavior of organic compounds and design new molecules with desired properties, making it a vital area of research in science.
