Résumé	Nucleophilic substitution reaction analysis is the systematic study of how nucleophiles attack electrophilic carbons (or other atoms), displacing leaving groups and forming new bonds. Formalized by Hughes, Ingold, and Winstein from the 1930s onward, this framework distinguishes mechanistic pathways (SN1 vs. SN2) and enables chemists to predict outcomes, optimize conditions, and design synthetic routes using substitution reactions.	Redox reaction mechanism analysis is the systematic study of electron transfer pathways in oxidation-reduction reactions. Formalized by Rudolph Marcus in the 1950s (earning him the Nobel Prize in 1992), this framework explains how electrons move between reactants, what factors control reaction rates, and how electronic and geometric factors influence the ease of electron transfer.
