Electrophilic attack is a fundamental concept in organic chemistry where an electrophile, a species that seeks electrons, reacts with a nucleophile, which is electron-rich. This interaction typically occurs in reactions involving alkenes, alkynes, or aromatic compounds, where the nucleophile donates a pair of electrons to the electrophile, forming a new bond. During this process, the electrophile can be a positively charged ion or a neutral molecule with a partial positive charge. The result of an electrophilic attack is often the formation of a more stable product, which can lead to various chemical transformations, such as substitution or addition reactions.
