In chemistry, a nucleophilic substitution is a class of chemical reactions in which an electron-rich chemical species (known as a nucleophile) replaces a functional group within another electron-deficient molecule (known as the electrophile). The molecule that contains the electrophile and the leaving functional group is called the substrate. The most general form of the reaction may be given as the following: Web24 sep. 2024 · A Nucleophilic Aromatic Displacement Reactions of Aryl Halides The carbon-halogen bonds of aryl halides are like those of alkenyl halides in being much stronger than those of alkyl halides.
