SN1 vs SN2 vs E1 vs E2 Predictor — Substitution & Elimination Mechanism Calculator
Pick a substrate class, nucleophile/base, solvent, and temperature, and instantly see which mechanism (SN1, SN2, E1, or E2) dominates — with the textbook reasoning spelled out for every pathway, plus the expected stereochemical and Zaitsev/Hofmann product outcome.

Topics Covered
- ✓Substrate class (methyl, 1°, 2°, 3°) and carbocation stability
- ✓Nucleophile vs base strength and steric bulk
- ✓Protic vs aprotic solvent effects
- ✓Heat shifting SN1↔E1 and SN2↔E2 product ratios
- ✓Inversion (SN2) vs racemization (SN1)
- ✓Zaitsev vs Hofmann elimination product
How to Use
- 1Select the substrate class, or toggle resonance-stabilization for allylic/benzylic cases
- 2Pick a real reagent (e.g. NaOH(aq), t-BuOK, NaI/acetone) and solvent
- 3Toggle heat and read the dominant/minor verdict for all 4 mechanisms with reasoning
