  2. Hydrogen disulfide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_disulfide

    The structure of hydrogen disulfide is similar to that of hydrogen peroxide, with C 2 point group symmetry. Both molecules are distinctly nonplanar. The dihedral angle between the H a −S−S and S−S−H b planes is 90.6°, compared with 111.5° in H 2 O 2. The H−S−S bond angle is 92°, close to 90° for unhybridized divalent sulfur. [1]

  3. Diboraanthracene - Wikipedia

    en.wikipedia.org/wiki/Diboraanthracene

    Frustrated lewis pair (FLP) compounds can also cleave dihydrogen in a conceptually similar manner, where the lewis acidic atom provides an acceptor orbital, and the lewis basic atom provides a filled orbital for back-donation. [1] [2] DBA can reversibly accept two electrons to form a doubly reduced dianion (DBA 2-) which acts as a main-group ...

  4. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    [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.

  5. Disulfide - Wikipedia

    en.wikipedia.org/wiki/Disulfide

    The structure of a disulfide bond can be described by its χ ss dihedral angle between the C β −S γ −S γ −C β atoms, which is usually close to ±90°. The disulfide bond stabilizes the folded form of a protein in several ways: It holds two portions of the protein together, biasing the protein towards the folded topology.

  6. Hydrogen sulfide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_sulfide

    Hydrogen sulfide is a chemical compound with the formula H 2 S.It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. [11]

  7. Dihydroxydisulfane - Wikipedia

    en.wikipedia.org/wiki/Dihydroxydisulfane

    Unlike many of these other reduced sulfur acids, dihydroxydisulfane can be formed in a pure state by reacting hydrogen sulfide with sulfur dioxide at −70 °C in dichlorodifluoromethane. [2] H 2 S + SO 2 → H 2 S 2 O 2. Dihyroxydisulfane may exist in an equilibrium with thiosulfurous acid. [3]

  8. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    MO diagram of dihydrogen Bond breaking in MO diagram. The smallest molecule, hydrogen gas exists as dihydrogen (H-H) with a single covalent bond between two hydrogen atoms. As each hydrogen atom has a single 1s atomic orbital for its electron, the bond forms by overlap of these two atomic orbitals. In the figure the two atomic orbitals are ...

  9. Organic sulfide - Wikipedia

    en.wikipedia.org/wiki/Organic_sulfide

    General structure of a sulfide with the blue marked functional group. In organic chemistry, a sulfide (British English sulphide) or thioether is an organosulfur functional group with the connectivity R−S−R' as shown on right. Like many other sulfur-containing compounds, volatile sulfides have foul odors. [1] A sulfide is similar to an ether ...
