| Feature | SN1 | SN2 |
|---|---|---|
| Kinetics | First order: $r = k[substrate]$ | Second order: $r = k[substrate][Nu^-]$ |
| Mechanism | Two-step (carbocation) | One-step (concerted) |
| Stereochemistry | Racemization | Inversion (Walden inversion) |
| Substrate | 3° > 2° > 1° | 1° > 2° >> 3° (steric) |
| Solvent | Polar protic | Polar aprotic |
$$SN1: racemization; SN2: Walden inversion$$

Why do we take the positive value only in the last step?
