16 gru 2021 · The discussion of resonance effect heavily relies on the understanding of resonance structures. Here we will focus on how to draw resonance structures (or resonance contributors) for organic chemistry species, and how to compare the relative stabilities between the structures.
Resonance (or delocalization) energy is the amount of energy needed to convert the true delocalized structure into that of the most stable contributing structure. The empirical resonance energy can be estimated by comparing the enthalpy change of hydrogenation of the real substance with that estimated for the contributing structure.
A stable optical resonator generally consists of two mirrors with radii of curvature p, and p2 separated by an optical distance L=nLo (Lo: geometrical mirror spacing, n: index of refraction inside the resonator).
Some resonance structures may be more stable than others; typically, structures that follow the octet rule and minimize formal charges are favored. Resonance is crucial in understanding properties like stability, reactivity, and the physical characteristics of many organic compounds.
Definition. Resonance structures are different ways to represent a molecule where the arrangement of electrons can vary, yet the connectivity of the atoms remains the same.
Some molecules have two or more chemically equivalent Lewis electron structures, called resonance structures. Resonance is a mental exercise and method within the Valence Bond Theory of bonding that describes the delocalization of electrons within molecules.
