Resonanzhybrid
Resonanzhybrid is the real electronic structure of a molecule that cannot be accurately described by a single Lewis structure but by a superposition of several contributing resonance structures. In valence bond theory, these canonical structures differ in how pi electrons and formal charges are arranged; the actual molecule is better represented by a weighted average of them, reflecting delocalized electrons.
In a resonance hybrid, electrons are not confined to a single bond or a single location. This
Contributions from different resonance structures are not directly measurable; however, chemists judge their importance by criteria
Common examples include benzene, where two Kekulé structures describe alternating double bonds, while the true structure
