Comparison of SN1 and SN2
- Base strength unimportant
- Substrates: reactivity order is 3o > 2o > 1o
- Solvent: good ionizing solvent required
- Rate: depends on substrate conc. only
- Stereochemistry: no particular geometry required for slow step; Saytzeff rule followed
- Rearrangements: very common
- Substrates: reactivity order is 3o > 2o > 1o
- Solvent polarity is not so important
- Rate: depends on conc. of substrate and base.
- Stereochemistry: coplanar arrangement required in transition state; Saytzeff rule followed
- Rearrangements: not possible
