  2. Sulfuric acid - Wikipedia

    en.wikipedia.org/wiki/Sulfuric_acid

    This type of reaction, where protonation occurs on an oxygen atom, is important in many organic chemistry reactions, such as Fischer esterification and dehydration of alcohols. Solid state structure of the [D 3 SO 4] + ion present in [D 3 SO 4] + [SbF 6] −, synthesized by using DF in place of HF.

  3. Desulfonation reaction - Wikipedia

    en.wikipedia.org/wiki/Desulfonation_reaction

    In organic chemistry, the desulfonation reaction is the hydrolysis of sulfonic acids: [1] RC 6 H 4 SO 3 H + H 2 O → RC 6 H 5 + H 2 SO 4. The reaction applied to aryl and naphthylsulfonic acids. It is the reverse of sulfonation. [2] The temperature of desulfonation correlates with the ease of the sulfonation.

  4. Oleum - Wikipedia

    en.wikipedia.org/wiki/Oleum

    Because of that, sulfuric acid is sometimes concentrated to oleum for in-plant pipelines and then diluted back to acid for use in industrial reactions. In Richmond, California in 1993 a significant release occurred due to overheating, causing a release of sulfur trioxide [ 6 ] that absorbed moisture from the atmosphere, creating a mist of ...

  6. Conjugate (acid-base theory) - Wikipedia

    en.wikipedia.org/wiki/Conjugate_(acid-base_theory)

    A conjugate acid, within the Brønsted–Lowry acid–base theory, is a chemical compound formed when an acid gives a proton (H +) to a base—in other words, it is a base with a hydrogen ion added to it, as it loses a hydrogen ion in the reverse reaction.

  7. Acid dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Acid_dissociation_constant

    It is the equilibrium constant for a chemical reaction + + known as dissociation in the context of acid–base reactions. The chemical species HA is an acid that dissociates into A −, called the conjugate base of the acid, and a hydrogen ion, H +.

  8. Arrow pushing - Wikipedia

    en.wikipedia.org/wiki/Arrow_pushing

    Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms. [1] It was first developed by Sir Robert Robinson.In using arrow pushing, "curved arrows" or "curly arrows" are drawn on the structural formulae of reactants in a chemical equation to show the reaction mechanism.

  9. Sulfonic acid - Wikipedia

    en.wikipedia.org/wiki/Sulfonic_acid

    General structure of a sulfonic acid with the functional group indicated in blue. In organic chemistry, sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O) 2 −OH, where R is an organic alkyl or aryl group and the S(=O) 2 (OH) group a sulfonyl hydroxide.
