  2. Butyric acid - Wikipedia

    en.wikipedia.org/wiki/Butyric_acid

    Isobutyric acid (2-methylpropanoic acid) is an isomer. Salts and esters of butyric acid are known as butyrates or butanoates. The acid does not occur widely in nature, but its esters are widespread. It is a common industrial chemical [7] and an important component in the mammalian gut.

  4. Isobutyric acid - Wikipedia

    en.wikipedia.org/wiki/Isobutyric_acid

    Isobutyric acid, also known as 2-methylpropanoic acid or isobutanoic acid, is a carboxylic acid with structural formula (CH 3) 2 CHCOOH. It is an isomer of butyric acid. It is classified as a short-chain fatty acid. Deprotonation or esterification gives derivatives called isobutyrates.

  5. Isomerization - Wikipedia

    en.wikipedia.org/wiki/Isomerization

    In one isomer the CO ligands are terminal. When a pair of CO are bridging, cis and trans isomers are possible depending on the location of the C 5 H 5 groups. [7] Another example in organometallic chemistry is the linkage isomerization of decaphenylferrocene, [(η 5-C 5 Ph 5) 2 Fe]. [8] [9] Formation of decaphenylferrocene from its linkage isomer

  6. Structural isomer - Wikipedia

    It is also extended to ionic compounds, so that (for example) ammonium cyanate [NH 4] + [O=C=N] − and urea (H 2 N−) 2 C=O are considered structural isomers, [4] and so are methylammonium formate [H 3 C−NH 3] + [HCO 2] − and ammonium acetate [NH 4] + [H 3 C−CO 2] −. Structural isomerism is the most radical type of isomerism.

  7. Ethyl acetate - Wikipedia

    en.wikipedia.org/wiki/Ethyl_acetate

    Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3 CO 2 CH 2 CH 3, simplified to C 4 H 8 O 2.This flammable, colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and the decaffeination process of tea and coffee.

  8. Ester - Wikipedia

    en.wikipedia.org/wiki/Ester

    Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials, and often have a pleasant characteristic, fruity odor. This leads to their extensive use in the fragrance and flavor industry.

  9. Metamerism (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Metamerism_(Chemistry)

    The isomers which have been cited as examples of metamers in chemical literature consist primarily of ethers; [3] but this could by the same reasoning be extended to thioethers, secondary as well as tertiary amines, esters, secondary as well as tertiary amides, (mixed) acid anhydrides etc. Metamers in organic chemistry
