Study Notes
Resonance in Organic Chemistry
- Resonance refers to a way of describing delocalization of electrons within a molecule, resulting in multiple Lewis structures that contribute to the actual structure of the molecule.
Definition of Resonance Structures
- Resonance structures are a set of two or more Lewis structures that have the same arrangement of atoms, but differ in the arrangement of electrons.
- These structures are separated by a double-headed arrow, indicating that they are resonance contributors.
Importance of Resonance Structures
- Resonance structures are important in organic chemistry because they help explain the unusual stability and reactivity of certain molecules.
- They also help account for the observed physical properties of molecules.
Characteristics of Molecules with Resonance Structures
- A molecule with resonance structures does not have a single fixed structure, but rather a hybrid of multiple structures.
- This results in a more stable molecule with delocalized electrons.
Representation of Resonance Structures
- A single Lewis structure representation signifies that the molecule does not have a fixed structure, but rather a hybrid of multiple structures.
- In resonance structures, the arrangement of atoms remains the same, while the arrangement of electrons changes.
