Substitution and elimination reactions

Sn1, Sn2, E1, and E2 reactions form the basis for understanding why certain products are more likely to form than others. We will learn about the reaction mechanisms, and how nucleophilicity and electrophilicity can be used to choose between different reaction pathways.
