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.

In this tutorial, Sal introduces free radical reactions by showing the reaction of methane with chlorine.

In this tutorial, Sal discusses the difference between nucleophilicity and basicity.

In this tutorial, Sal explains the difference between an E1 and an E2 elimination reaction.

In this tutorial, Sal compares the differences between SN1, SN2, E1, and E2 reactions.
