Answer :
Final answer:
The statement that resonance structures increase a compound's energy is false. Resonance actually describes electron delocalization, which stabilizes a molecule through multiple contributing structures, resulting in a resonance hybrid that is lower in energy.
Explanation:
The concept of resonance structures in chemistry is often misunderstood. The statement "Resonance structures happen so the compound can have a higher energy" is false.
Instead, resonance occurs when a molecule can be represented by two or more valid Lewis structures, also known as resonance contributing structures.
Resonance stabilizes the molecule since the true structure is a resonance hybrid of these contributing structures, which has a lower, more stable energy than any individual contributing structure.
This phenomenon reflects the delocalization of electrons across the molecule. When considering resonance in a molecule, the multiple structures simply help us predict the actual form of the molecule, which is more stable due to this electron delocalization.
Therefore, the true importance of resonance in chemistry is to provide a more accurate description of electron distribution within molecules that cannot be represented by a single Lewis structure.
More stable resonance forms contribute more to the resonance hybrid, leading to a structure that is more stable (lower in energy) than any individual resonance contributing structure.
The result is a molecule with electron delocalization leading to overall increased stability, which is especially important in certain reactions, such as those involving aromatic compounds.
