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.	Substitution reaction kinetics analysis is the systematic study of how fast nucleophiles replace leaving groups in organic and inorganic compounds. Formalized by Edward Hughes and Christopher Ingold in the 1930s, this framework distinguishes between bimolecular (SN2) and unimolecular (SN1) mechanisms, connecting mechanism to reaction rates, and enabling prediction of reactivity based on substrate structure, nucleophile strength, and solvent effects.
