What are the basic types of organic chemical reactions?

The basic types of organic chemical reactions primarily include addition, elimination, and substitution, which are essential processes in organic chemistry.

Addition reactions involve the combination of two or more reactants to form a single product. This frequently occurs with unsaturated compounds, like alkenes and alkynes, where multiple bonds are broken to allow for new atoms or groups to attach, thereby increasing the molecular complexity.

Elimination reactions, on the other hand, involve the removal of a small molecule from a larger one, leading to the formation of a double or triple bond. This typically occurs when a single molecule loses atoms or groups, resulting in a more simplified structure.

Substitution reactions entail the replacement of one atom or group in a molecule by another atom or group. This reaction is crucial for modifying the properties of organic compounds without changing their fundamental structure.

Together, these reactions form a foundational understanding of how organic molecules interact, allowing for the synthesis and modification of a vast array of organic compounds. As such, this trio of reaction types is crucial for students of organic chemistry to master, as they underpin many principles and applications in the field.
