[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
In chemistry, dioxirane (systematically named dioxacyclopropane, also known as methylene peroxide or peroxymethane) is an organic compound with formula CH 2 O 2.The molecule consists of a ring with one methylene and two oxygen atoms.
(a) The LDQ structure of the B 2 H 6 molecule. The nuclei are as indicated and the single electrons are denoted by dots. The thick lines denote coincident electron pairs. (b) The traditional valence bond theory structure for the B 2 H 6 molecule. The thin curved lines stretching across the boron-hydrogen-boron moiety indicate that the two ...

A valence bond structure resembles a Lewis structure, but when a molecule cannot be fully represented by a single Lewis structure, multiple valence bond structures are used. Each of these VB structures represents a specific Lewis structure. This combination of valence bond structures is the main point of resonance theory.
2,3,4,6-Tetrachlorophenol (2,3,4,6-TCP) is a chlorinated derivative of phenol with the molecular formula C 6 H 2 Cl 4 O. References Cited sources. Haynes, William M ...
1,3,4,6-Tetrathiapentalene-2,5-dione or thiapendione is a chemical compound with a formula C 4 O 2 S 4. It is a dithiole containing two carbonyl groups that is used in the synthesis of sulfur heterocyclic compounds .
The structure of the tetrathionate anion. The tetrathionate anion, S 4 O 2− 6, is a sulfur oxyanion derived from the compound tetrathionic acid, H 2 S 4 O 6. Two of the sulfur atoms present in the ion are in oxidation state 0 and two are in oxidation state +5. Alternatively, the compound can be viewed as the adduct resulting from the binding ...
