  2. Schiff test - Wikipedia

    en.wikipedia.org/wiki/Schiff_test

    The mechanism was proposed in 1921 by the eminent German organic chemist Heinrich Wieland and his student Georg Scheuing (1895–1949). [10] [11] Bisulphite was believed to react with the available aromatic amine functional groups to form N-sulfinic acid groups, Ar-NH-SO 2 H, followed by reaction with aldehyde to form sulfonamides, Ar-NH-SO 2 CH

  3. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    The reactivity of a functional group can be modified by other functional groups nearby. Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis. A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. The atoms in a ...

  4. Organic azide - Wikipedia

    en.wikipedia.org/wiki/Organic_azide

    The azide functional group can be shown by two resonance structures. An organic azide is an organic compound that contains an azide (– N 3) functional group. [1] Because of the hazards associated with their use, few azides are used commercially although they exhibit interesting reactivity for researchers.

  5. Transesterification - Wikipedia

    en.wikipedia.org/wiki/Transesterification

    Transesterification is the process of exchanging the organic functional group R″ of an ester with the organic group R' of an alcohol. These reactions are often catalyzed by the addition of an acid or base catalyst. [1] Strong acids catalyze the reaction by donating a proton to the carbonyl group, thus making it a more potent electrophile.

  6. List of reagents - Wikipedia

    en.wikipedia.org/wiki/List_of_reagents

    organic compound; often used as a foamer in plastics and rubber and as a radical initiator: Baeyer's reagent: is an alkaline solution of potassium permanganate; used in organic chemistry as a qualitative test for the presence of unsaturation, such as double bonds; N-Bromosuccinimide

  7. Organophosphate - Wikipedia

    en.wikipedia.org/wiki/Organophosphate

    General chemical structure of the organophosphate functional group. In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure O=P(OR) 3, a central phosphate molecule with alkyl or aromatic substituents. [1] They can be considered as esters of phosphoric ...

  8. End group - Wikipedia

    en.wikipedia.org/wiki/End_group

    End groups are seen on all polymers and the functionality of those end groups can be important in determining the application of polymers. Each type of polymerization (free radical, condensation or etc.) has end groups that are typical for the polymerization, and knowledge of these can help to identify the type of polymerization method used to form the polymer.

  9. Acetoxy group - Wikipedia

    en.wikipedia.org/wiki/Acetoxy_group

    The structure of the acetoxy group blue. In organic chemistry, the acetoxy group (abbr. AcO or OAc; IUPAC name: acetyloxy [1]), is a functional group with the formula −OCOCH 3 and the structure −O−C(=O)−CH 3. As the -oxy suffix implies, it differs from the acetyl group (−C(=O)−CH 3) by the presence of an additional oxygen atom.
