Curriculum Module NSR

Nucleophilic Substitution Reactions

SN1, SN2, SNi Pathways, Leaving Groups, Solvolysis & Walden Inversion

115 SlidesFull Master Compendium

Core Mechanistic Pathways

SN1 vs SN2 decision matrix: Substrate, Nucleophile, Solvent, Leaving Group
Kinetics: 1st order vs 2nd order rate laws
Walden inversion in SN2 back-side displacement
Racemization vs retention in SN1 carbocation solvolysis
SNi mechanism with Thionyl Chloride (SOCl₂) with and without Pyridine
Neighboring Group Participation (NGP / anchimeric assistance)

Key Reagents & Conditions

Polar protic vs polar aprotic solvents (DMSO, DMF, acetone)NaI in acetone (Finkelstein)AgF (Swarts)SOCl₂, PCl₅, PBr₃

Stereochemical Dynamics

100% optical inversion in pure bimolecular SN2; partial racemization with net inversion in SN1 contact ion pairs.

Module Summary & Study Guidance

Deep dive into aliphatic nucleophilic substitutions. Complete reagent matrices, transition state geometry, solvent dielectric impacts, and kinetic competition analysis.

Exam Orientation: JEE Main & Advanced · Alkyl Halides foundation. All materials are embedded directly on Chem-Mantra with online presentation and secure reference reading modes.
