SnCl 2 has a lone pair of electrons, such that the molecule in the gas phase is bent.In the solid state, crystalline SnCl 2 forms chains linked via chloride bridges as shown. . The dihydrate has three coordinates as well, with one water on the tin and another water on the fi
The bimolecular nucleophilic substitution (S N 2) is a type of reaction mechanism that is common in organic chemistry. In the S N 2 reaction, a strong nucleophile forms a new bond to an sp 3-hybridised carbon atom via a backside attack, all while the leaving group detaches from the reaction center in a concerted (i.e. simultaneous) fashion.
Homonuclear triatomic molecules contain three of the same kind of atom. That molecule will be an allotrope of that element. Ozone, O 3 is an example of a triatomic molecule with all atoms the same. Triatomic hydrogen, H 3, is unstable and breaks up spontaneously. H 3 +, the trihydrogen cation is stable by itself and is symmetric.
Bent's rule can be extended to rationalize the hybridization of nonbonding orbitals as well. On the one hand, a lone pair (an occupied nonbonding orbital) can be thought of as the limiting case of an electropositive substituent, with electron density completely polarized towards the central atom.
This study found that a high percentage of people with type 2 diabetes tend to be deficient in three micronutrients: vitamins D and B12 and magnesium. These are also commonly deficient nutrients ...
In chemistry, the trigonal prismatic molecular geometry describes the shape of compounds where six atoms, groups of atoms, or ligands are arranged around a central atom, defining the vertices of a triangular prism. The structure commonly occurs for d 0, d 1 and d 2 transition metal complexes with covalently-bound ligands and small charge ...
Princess Anne made a special visit to the hospital where she was treated after a horse-related accident to thank the staff who looked after her.. On Feb. 6, the Princess Royal, 74, returned to ...
An Aurora, Colorado judge granted the 'emergency closure' of The Edge at Lowry Apartments after multiple arrests and rumored gang activity.
