Resonance Structures

Representations of a molecule showing different electron distributions, but the actual molecule is a hybrid of these.

Major Contributor

The most significant structure or mechanism among several possibilities in a chemical reaction or process.

Resonance Hybrid

A representation of a molecule where the electron distribution is a hybrid of two or more structures, illustrating the delocalization of electrons.
