  2. 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.

  3. Ammonium chloride - Wikipedia

    en.wikipedia.org/wiki/Ammonium_chloride

    Ammonium chloride is used in a ~5% aqueous solution to work on oil wells with clay swelling problems. Other uses include in hair shampoo, in the glue that bonds plywood, and in cleaning products. In hair shampoo, it is used as a thickening agent in ammonium-based surfactant systems such as ammonium lauryl sulfate. Ammonium chloride is used in ...

  4. Lewis acids and bases - Wikipedia

    en.wikipedia.org/wiki/Lewis_acids_and_bases

    In a Lewis adduct, the Lewis acid and base share an electron pair furnished by the Lewis base, forming a dative bond. [1] In the context of a specific chemical reaction between NH 3 and Me 3 B, a lone pair from NH 3 will form a dative bond with the empty orbital of Me 3 B to form an adduct NH 3 •BMe 3.

  5. Salt (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Salt_(chemistry)

    In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions and negatively charged ions , [1] which results in a compound with no net electric charge (electrically neutral). The constituent ions are held together by electrostatic forces termed ionic bonds.

  6. Natural resonance theory - Wikipedia

    en.wikipedia.org/wiki/Natural_Resonance_Theory

    The LEWIS option tests each structure and rejects those that do not conform to the Lewis bonding theory (i.e., those that do not fulfill the octet rule, pose unreasonable formal charges, etc.). (2) The PARENT and CHOOSE operations determine the optimal set of NBOs corresponding to a specific resonance structure.

  7. Chloramines - Wikipedia

    en.wikipedia.org/wiki/Chloramines

    Chloramines refer to derivatives of ammonia and organic amines wherein one or more N−H bonds have been replaced by N−Cl bonds. [1] [2] Two classes of compounds are considered: inorganic chloramines and organic chloramines. Chloramines are the most widely used members of the halamines. [3]

  8. Ionic bonding - Wikipedia

    en.wikipedia.org/wiki/Ionic_bonding

    Thus, bonding is considered ionic where the ionic character is greater than the covalent character. The larger the difference in electronegativity between the two types of atoms involved in the bonding, the more ionic (polar) it is. Bonds with partially ionic and partially covalent character are called polar covalent bonds. For example, Na–Cl ...

  9. Monochloramine - Wikipedia

    en.wikipedia.org/wiki/Monochloramine

    NH 2 Cl + NH 3 + NaOH → N 2 H 4 + NaCl + H 2 O. Chloramine electrophilically aminates itself in neutral and alkaline media to start its decomposition: 2 NH 2 Cl → N 2 H 3 Cl + HCl. The chlorohydrazine (N 2 H 3 Cl) formed during self-decomposition is unstable and decomposes itself, which leads to the net decomposition reaction: 3 NH 2 Cl → ...
