Characteristics of Resonance

Characteristics of resonance are important to understand the resonance structure in detail. In comparison, characteristics of magnetic resonance imaging is a technique applied in radiology and nuclear medicines. It differs in characteristics where it is applied. Certain molecules bonding is described in the resonance structure as one of the important characteristics of resonance in chemistry.

Resonance is also recognised as a mesomerism in chemistry. Resonance is one of the ways of explaining the bonding of certain ions or molecules with the help of several contributing structures. According to the valence bond theory, these structures are termed a resonance structure into a resonance hybrid.

What Is Resonance?

Resonance structure arrives when the single lewis structure can not explain the bonding of certain molecules or ions. Resonance hybrid means the combination of the possible resonance structures and characteristics of Resonance. This resonance structure explains the displacement of the electrons within the molecules. In contrast, Magnetic resonance uses magnetic fields and radiofrequency to produce imaging; these characteristics have been applied in diagnosing clinical conditions. Resonance hybrid describes the characteristic properties of the molecule’s resonance in chemistry. The resonance hybrid is more stable than that of the contributing forms. It has lower energy than any contributing form of molecules. The resonance hybrid’s energy difference forming a more stable contributing structure is resonance energy. Resonance is a molecule structure between two structures of molecules at one electron dot. Resonance structures allow molecules to attain stability because they allow their electrons to lengthen their wavelength. And it allows them to lower their energy.

The mainly important Characteristics of resonance:-

1. Resonance includes the dislocation of electrons in similar atomic nuclei.
2. When all atoms lie in a similar plane, only resonance will happen.
3. The same number of paired and unpaired electrons should be a part of a resonating structure.
4. Resonating structure energy should be nearly similar.
5. More stable contributing forms can achieve the representation of actual molecules. The more stable contributing forms achieve more stability. It is one of the essential characteristics of resonance to pay attention to.
6. All the negative and positive charges should be present on electronegative and electropositive atoms.
7. All the charges should not reside on the adjacent.
8.  Contributing structures do not have any value. They are considered imaginary, and actual resonance structures will exist.
9. Bond length becomes similar due to the resonance energy.
10.  Higher the resonance energy, the higher the stability of the molecules.

Magnetic resonance imaging is one technique used to view the internal organs of the human body through radio frequency and magnetic fields. It uses an important characteristic property of the non-invasive method to have an image of internal human organs, tissue, bones, and structures. It can produce cross-sectional images and 3D images as well. Radiation is not used like X-rays and CT scans.

Magnetic resonance imaging is a crucial part of the diagnosis of disease. Most doctors prescribe the Magnetic resonance imaging technique over x-ray, ct scan, and ultrasound due to its non-radiation characteristics that make it a more important part of the diagnosis. Magnetic resonance is based on the magnetic properties of the atomic nuclei.

Characteristics Of Magnetic resonance imaging:-

1. It allows an image of a body part without the involvement of radiation.
2. It uses the application of magnetic fields and radiofrequency.
3. It can provide cross-sectional and 3D images.
4. Radio waves help to produce an image.
5. It allows the image of body parts that can not be taken by CT scan or X-ray.
6. Five major image characteristics can be seen:- the quality of an image, control sensitivity, details, noise, artefacts and most important, spatial.

In this article, various resonance characteristics and characteristics of magnetic resonance imaging have been explained. It will be beneficial for chemistry students to understand the concept of resonance and its characteristics.

Magnetic resonance imaging techniques have wide application in clinical condition diagnosis. It helps find cancer and prevent the spread of cancer among the patients. It is the most liked technique by doctors. Also, do not use radiation to reduce the risk of patient exposure to radiation.  It is one of the non-invasive methods. Provides an extremely clear image of soft tissues, which can not be achieved by other ways like CT scans or X-Ray.

Conclusion

This article describes an overview of resonance, characteristics of Resonance and magnetic resonance imaging. Resonance is a molecule structure between two structures of molecules at one electron dot. Resonance structures allow molecules to attain stability because they allow their electrons to lengthen their wavelength. And it allows them to lower their energy.

Resonance stability plays a vital role in organic chemistry. Because the resonant molecules reduce the energy of formation, organic chemistry students must understand the effects and practice spotting molecules that are stabilised by resonance forms. Characteristics of resonance, a study of the resonance structure, helps organic chemistry students understand resonance concepts.
