# Substitution Reactions

This page lists the learning units from the topic "Substitution Reactions" in a reasonable order with regard to contents.

## Substitution Reactions

### $SN2$ - Second-order Nucleophilic Substitution 60 min.

This learning unit deals with second-order nucleophilic substitutions ($SN2$). The mechanism, applications, and parameters that influence the $SN2$ reaction are discussed.

### $SN1$ - First-order Nucleophilic Substitution 45 min.

This learning unit deals with first-order nucleophilic substitutions ($SN1$). The mechanism, applications, and parameters that influence the $SN1$ reaction are discussed.

### SN/E Competition - $SN2$/$E2$ Competition 40 min.

First, this learning unit describes the mechanistic reasons for the competition of elimination and nucleophilic substitution. Then, the different parameters that influence the $SN2$/$E2$ competition are discussed. After working through the learning unit, one should be able to predict, depending on given parameters, the predominant mechanism of a reaction or to choose the parameters of a reaction, so that a mechanism desired actually mainly occurs, respectively.

### SN/E Competition - $SN1$/$E1$ Competition 30 min.

First, this learning unit describes the mechanistic reasons for the competition of elimination and nucleophilic substitution. Then, the different parameters that influence the $SN1$/$E1$ competition are discussed. After working through the learning unit, one should be able to predict, depending on given parameters, the predominant mechanism of a reaction or to choose the parameters of a reaction, so that a mechanism desired actually mainly occurs, respectively.

### SN/E Competition - Role of the Temperature 20 min.

First, this learning unit describes the mechanistic reasons for the competition of elimination and nucleophilic substitution. Then, the influence of the reaction temperature on the $SN2$/$E2$ competition as well as the $SN1$/$E1$ competition is discussed.
