Are Canonical Structures Real?

The canonical forms have no real existence. ... The molecule as such has a single structure which is the resonance hybrid of the canonical forms and which cannot as such be depicted by a Lewis structure

Lewis structure
The Lewis structure was named after Gilbert N. Lewis, who introduced it in his 1916 article The Atom and the Molecule. Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

What is a canonical structure?

in chemistry, canonical structures is a way of representing or describing the delocalized electrons within certain molecules or polyatomic ions (like is sulfate, phosphate ions) where the bonding cannot be expressed in terms of single lewis structure.

Do canonical structures have same energy?

Resonance energy will be more if Canonical structure are equivalent than if canonical structure and non- equivalent for the same species . Molecule is aromatic than le is not aromatic .
