Diagnostic Comparison & Property Matrix
| Parameter / Feature | Standard State / Condition A | Altered State / Condition B |
|---|---|---|
| Driving Force | Thermodynamic control (more stable product) | Kinetic control (lower activation barrier) |
| Solvent Dependency | Polar protic solvent stabilizes charge separation | Polar aprotic solvent accelerates bare nucleophilicity |
| Temperature Influence | High temperatures favor elimination / endothermic | Mild temperatures favor addition / exothermic |
| Common Pitfall | Overlooking rearrangement or stereochemical inversion | Neglecting boundary limits or stoichiometric coefficients |
