In this research, we use AIM theory (Baders Atoms In Molecules) coupled with high quality quantum mechanical calculations to examine the mathematical form of bond-valence-bond-length correlations. There are many mathematical similarities in the description of bonding in these two theories: both ...
Is NO2 an ionic or covalent bond? What atoms does actinium bond with? Is a hydrogen bond stronger than a covalent bond? Which type of bond will form between two chlorine atoms? What is the definition of bond in chemistry? Does oxygen form ionic or covalent bonds? Which atom is most lik...
To bond or not to bond? One of the key ambiguities in chemical bonding lies with the relationship between the strength and length of a bond. Chemists are accustomed to the idea that strong bonds tend to be short, and weak ones long. But this doesn’t always seem to mean that atoms tha...
A double bond is a type of chemicalbondin which twoelectronpairs are shared between twoatoms. This type of bond involves four bonding electrons between atoms, rather than the usual two bonding electrons involved in a single bond. Because of the large number of electrons, double bonds tend to ...
What is a sigma (σ) bond in chemistry?Question:What is a sigma (σ) bond in chemistry? Covalent Bond:The chemical bond is formed by sharing or equal distribution of electrons between two atoms is known as a covalent bond. As atomic orbitals exhibit directional properties covalent bond has ...
Advanced theory of the hydrogen bondThe hydrogen bond remains a fairly mysterious object in the theoretical study of quantum chemistry and physics. Most generally, the hydrogen bond can be viewed as a metric dependent electrostatic scalar field between two or more intermolecular bonds. This is ...

if we have 1,2-dibromocyclohexene (double bond is between 1 and 2 carbon) and we add H2 over Pt, what is the final product? Relevant Equations - I think that the double bond would be broken in some way but what happens to the two bromines? do they remain in the ring? (or does...
where L is the length of the chemical bond, and Δp is the quantum mechanical uncertainty of the momentum of each electron in a given chemical bond. Whence, we obtain a formula for determining the uncertainty of the momentum in a chemical bond: ...
Chemistry class (Photo Credit : Elegant Solution/Shutterstock) When you see a molecular diagram or read a molecular formula, it may not immediately be apparent whether you are seeing a molecule or a compound. In fact, you may not even know if there is a difference between these two designati...
