  2. Sulfate - Wikipedia

    en.wikipedia.org/wiki/Sulfate

    Therefore, the representation with four single bonds is the optimal Lewis structure rather than the one with two double bonds (thus the Lewis model, not the Pauling model). [6] In this model, the structure obeys the octet rule and the charge distribution is in agreement with the electronegativity of the atoms. The discrepancy between the S−O ...

  3. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

  4. Sulfation - Wikipedia

    en.wikipedia.org/wiki/Sulfation

    Sulfation is widely used in the production of consumer products such as detergents, shampoos, and cosmetics. Since the sulfate group is highly polar, its conjugation to a lipophilic "tail" gives surfacant-like properties.

  5. Tetrahedral molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Tetrahedral_molecular_geometry

    In a tetrahedral molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron.The bond angles are arccos(− ⁠ 1 / 3 ⁠) = 109.4712206...° ≈ 109.5° when all four substituents are the same, as in methane (CH 4) [1] [2] as well as its heavier analogues.

  6. Lewis acids and bases - Wikipedia

    en.wikipedia.org/wiki/Lewis_acids_and_bases

    For example, NH 3 is a Lewis base, because it can donate its lone pair of electrons. Trimethylborane [(CH 3) 3 B] is a Lewis acid as it is capable of accepting a lone pair. In a Lewis adduct, the Lewis acid and base share an electron pair furnished by the Lewis base, forming a dative bond. [1]

    Intel said on Wednesday its deal for $7.86 billion in U.S. government subsidies restricts the company's ability to sell stakes in its chipmaking unit if it becomes an independent entity. The U.S ...

  8. Sulfur monoxide - Wikipedia

    en.wikipedia.org/wiki/Sulfur_monoxide

    The SO molecule has a triplet ground state similar to O 2 and S 2, that is, each molecule has two unpaired electrons. [2] The S−O bond length of 148.1 pm is similar to that found in lower sulfur oxides (e.g. S 8 O, S−O = 148 pm) but is longer than the S−O bond in gaseous S 2 O (146 pm), SO 2 (143.1 pm) and SO 3 (142 pm).
