Nature tends to be lazy, and would rather not carry a charge at all if possible. A major contributor, like III, provides the best match. Major contributing structure is "C". While setting up vibrations at other frequencies is possible, they require much more energy and constant input to maintain than a resonanc. This is important because neither resonance structure actually exists, instead there is a hybrid. When assigning hybridization states to atoms in a molecule, all minor resonance contributors are. Which resonance structure below is the major contributor? arrow_forward. 3D: Major vs minor resonance contributors Different resonance contributors do not always make the same contribution to the overall structure of the hybrid - rather, in many cases one contributor comes closer to depicting the actual bonding picture than another. Identify the major and minor resonance contributor(s) for the azide anion, N3?. There are three equivalent resonance structures for CO32-, and the actual structure of CO32-is a hybrid of the three resonance contributors.

Conversely, resonance contributors with positive charge on highly electronegative atoms score lower than ones with positive charge on non electronegative atoms. While both resonance structures are chemically identical, the negative charge is on a different oxygen in each. A third way to illustrate the carbon-oxygen dipole is to consider the two main resonance contributors of a carbonyl group: the major form, which is what you typically see drawn in Lewis structures, and a minor but very important contributor in which both electrons in the pbond are localized on the oxygen, giving it a full negative charge. The formate anion, or #"HCO"_2^(-)#, has two major and one minor contributors to its hybrid structure.
