resonance structure उदाहरण वाक्य

Structures 2a to 2c are three resonance structures that can be drawn for this species, two of which have enolate ions.
When comparing resonance structures for the same molecule, usually those with the fewest formal charges contribute more to the overall resonance hybrid.
In reaction conditions that favor a S N 1 reaction mechanism the intermediate is a carbocation for which several resonance structures are possible.
The electromagnetic ( isotropic ) metamaterials have built-in resonance structures that exhibit effective negative permittivity and negative permeability for some frequency ranges.
Of course this is at cost to benzene's own ability to have multiple resonance structures, so there's a tradeoff.

The sigma bond between the ring and carboxyl group is then severed, the electron pair moving to the ring and delocalized through resonance structures.
The molecule cannot be represented by one structure, but rather a resonance hybrid of different structures, such as with the two resonance structures of benzene.
When this situation occurs, the molecule's Lewis structure is said to be a resonance structure, and the molecule exists as a resonance hybrid.
When formal charges are necessary, resonance structures that have negative charges on the more electronegative elements and positive charges on the less electronegative elements are favored.
It X-ray crystallographic and nuclear magnetic resonance structure studies have shown how this binding distorts the DNA by perturbing the double-helical DNA structure.
