Nucleophiles, Electrophiles, Leaving Groups, and the SN2 Reaction

Professor Dave explains the SN2 reaction, a type of nucleophilic substitution where a nucleophile replaces a leaving group on a substrate. The video covers the key players: nucleophile, electrophile, and leaving group, and details the reaction mechanism, emphasizing the importance of electron-pushing arrows. It also discusses the geometric aspects, including the transition state and stereochemistry inversion, highlighting the bimolecular nature of the SN2 reaction.
