Final answer:
B) Stabilization. Resonance stabilization is the term that describes the increased stability of a molecule due to the delocalization of electrons over all possible bonds, represented by multiple resonance structures.
Step-by-step explanation:
Resonance stabilization describes a condition in which extra electrons are delocalized over all possible bonds. This delocalization results in more bonding, where electrons are spread over multiple nuclei, leading to a decrease in potential energy.
The concept of resonance helps in understanding the structure of molecules like ozone (O3), where bonding cannot be represented by just one Lewis structure. Instead, multiple resonance structures are used to describe the bonding more accurately.
These structures collectively represent the actual bonding situation and the real structure of the molecule is seen as a resonance hybrid, more stable than individual contributing structures due to resonance stabilization.
