Summary of S N 1 and S N 2

Substitution vs Elimination Many nucleophiles are also strong bases (OH - and RO - ) and S N and E reactions often compete –the ratio of S N /E products depends on the relative rates of the two reactions What favors Elimination reactions: - attacking nucleophil is a strong and large base - steric crowding in the substrate - High temperatures and low polarity of solvent
