Elimination Vs Substitution Reaction
The key diferences between elimination and substitution reaction are listed in the following table:
| Characteristic | Elimination Reaction | Substitution Reaction |
|---|---|---|
| Objective | To remove two groups from a molecule. | To replace one group with another. |
| Type of Reagents | Often involves a base as a reagent. | Involves a nucleophile or electrophile. |
| Number of Reactant Groups | Typically involves one reactant group. | Typically involves two reactant groups. |
| Types of Products | Produces a new π bond (alkenes or alkynes). | Produces a different compound entirely. |
| Mechanism | E1, E2, or E1cB mechanisms are common. | SN1, SN2, or SNi mechanisms are common. |
| Stereochemistry | Can lead to the formation of stereoisomers. | Often leads to inversion or retention. |
| Conditions | Often requires strong bases and elevated temperatures. | Varies depending on the specific reaction. |
| Examples | Dehydrohalogenation, dehydrations, dehalogenations. | Nucleophilic and electrophilic substitutions. |

Substitution Reaction
Substitution Reaction as the name suggests tells us about the reaction in which some functional group is substituted by the other functional group. Substitution Reaction play a crucial role in the synthesis, modification, and functionalization of organic compounds, allowing chemists to form compounds with specific properties and reactivity of molecules for various applications.
In this article, we will discuss all things related to Substitution Reaction i.e., its definition, and examples including Alkane Substitution, Nucleophilic, Electrophilic, Free Radical as well as Organomatelic Substitution.
