Molecular orbital theory

INTRODUCTION The Molecular Orbital Theory (frequently shortened to MOT) is a hypothesis on compound bonding created toward the start of the 20th century by F. Hund and R. S. Mulliken to depict the design and properties of various particles. The valence-bond hypothesis neglected to satisfactorily clarify how certain atoms contain at least two identical bonds […]

In molecular orbital theory, electrons in a molecule are not assigned to individual chemical bonds between atoms but are treated as moving under the influence of the atomic nuclei in the whole molecule. The molecular orbital model is by far the most prolific of the various different chemical bonding models, and it serves as the foundation

Molecular orbital theory- The molecular orbital theory or the MOT is a way of explaining the electronic structure of atoms and molecules using quantum mechanics. The basic principle of this theory is that as atoms bond to form molecules, a particular number of atomic orbitals merge to create the same number of molecular orbitals, although

Introduction  Molecules formed from two atoms per molecule are known as diatomic molecules. The molecules thus formed are attracted to each other with the help of covalent chemical bonds. Remember, the atoms combined can be with the help of a single bond, double bond, and triple bond. Depending on the types of atoms used during

It should be mentioned that Mohr’s salt is named after the German chemist Karl Friedrich Mohr, who discovered the element. When dissolved in water, Mohr’s salt (as well as most other salts of ferrous sulphate) dissolves to create an aquo complex with the chemical formula [Fe(H2O)6]2+. It should also be noted that the molecular geometry

Elements constantly try to get eight electrons in the outermost or the valence shell. In order to get all eight electrons in their respective valence shells, atoms form bonds with their most compatible atoms either by donating or sharing electrons. A metallic bond can be described as a bond where there are several metallic atoms

Overview of bond length When two atoms form a covalent bond, the distance between their centres is called bond length. Bond order is determined by the number of bonds, based on the number of electrons. The bond length and bond order are inversely related to each other. Bond length is generally measured on a picometre

Bond isomerism occurs with binary ligands that can coordinate in a variety of ways. The most famous cases involve monodentate ligands: SCN-/NCS- and NO2-/ONO-. The only difference is which atoms bind the molecular ligand to the central ion. The ligand must have more than one donor atom, but can only bind the ion in one

Introduction The covalent bonding in complexes is ignored in crystal field theory, which treats ligands as point-charged or dipoles. Rather, it considers the bonding to be solely ionic. The measurements like electron spin resonance or electron paramagnetic resonance, nuclear magnetic resonance, nuclear quadrupole resonance, and Racah parameters calculations using electronic spectra show that coordination compounds

Ketones are found all over the world and are frequently coupled with other functional groups. The group can be found in almost all biological substances. Carbohydrates, lipids, proteins, nucleic acids, hormones, and vitamins are examples of organic substances important to living systems. Two carbon groups are connected to the carbonyl carbon atom in a ketone.
