| E | SN | ||
| Reaction order | Favored by strong bases | Not favored by strong bases | |
| 1 | Favored by steric hindrance |
E1 e.g. R3C-X |
SN1 e.g. R3C-X in non-basic solvents |
| 2 | Not favored by steric hindrance |
E2 e.g. R2CH-X with strong base, R3C-X with strong base |
SN2 e.g. CH3-X, RCH2-X (Not R3C-X) |
