Exceptions to the Octet Rule

Many covalent molecules have central atoms that do not have eight electrons in their Lewis structures. These molecules fall into three categories:

Lewis Symbols and the Octet Rule

Chemical bonds are complex interactions between two or more atoms or ions, which reduce the potential energy of the molecule. Gilbert N. Lewis developed a model called the Lewis model that simplified the depiction of chemical bond formation and provided straightforward explanations for the chemical bonds seen in most common compounds.

Valence Bond Theory

8.5K
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

3.1K
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...

Five-Membered Heterocyclic Aromatic Compounds: Overview

3.9K
Heterocyclic aromatic compounds are cyclic compounds that are aromatic and have one or more heteroatoms—atoms other than carbon, in the ring. Depending upon the number of atoms present in the ring, they can be either five or six-membered. Examples of five-membered heterocyclic aromatic compounds include pyrrole, furan, thiophene, and imidazole. Pyrrole consists of one nitrogen atom having one lone pair of electrons. Furan and thiophene have one oxygen and one sulfur heteroatom,...

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Retinal Diseases

Background:

  • Optical coherence tomography angiography (OCTA) is a non-invasive imaging technique developed in 2005.
  • OCTA provides high-resolution, depth-resolved imaging of ocular vasculature.
  • It offers advantages over traditional fluorescein angiography (FA) in terms of speed and safety.

Purpose of the Study:

  • To review the transformative role of OCTA in diagnosing and managing diverse eye conditions.
  • To highlight OCTA's utility in specific diseases like diabetic retinopathy, AMD, RVO, and white dot syndromes.
  • To explore emerging applications of OCTA in neurodegenerative diseases.

Main Methods:

  • Review of existing literature and clinical applications of OCTA.
  • Comparison of OCTA with traditional fluorescein angiography (FA).
  • Discussion of OCTA's capabilities in visualizing microvascular changes and quantifying metrics like perfused capillary density (PCD).

    • Main Results:

    • OCTA enables early detection of retinal changes in diabetic retinopathy, with quantifiable metrics.
    • It enhances understanding and monitoring of non-exudative neovascular AMD.
    • OCTA reveals prognostic microvascular features in retinal vein occlusions and aids in differentiating white dot syndromes.

    Conclusions:

    • OCTA is revolutionizing ophthalmic diagnostics and management across a spectrum of eye diseases.
    • Its non-invasive nature and detailed imaging offer significant advantages over conventional methods.
    • Further clinical trials and standardization are necessary for broader clinical adoption.
