In organic chemistry, compounds composed of carbon and hydrogen are divided into two classes: aromatic compounds, which contain benzene or similar rings of atoms, and aliphatic compounds (; G. aleiphar, fat, oil ), which do not contain those rings.

During this period significant analytical contributions to chemistry include the development of systematic elemental analysis by Justus von Liebig and systematized organic analysis based on the specific reactions of functional groups.

Starting in approximately the 1970s into the present day analytical chemistry has progressively become more inclusive of biological questions ( bioanalytical chemistry ), whereas it had previously been largely focused on inorganic or small organic molecules.

In organic chemistry, an alkene, olefin, or olefine is an unsaturated chemical compound containing at least one carbon-to-carbon double bond.

The later discovery of Friedrich Wöhler that many natural substances, organic compounds, can indeed be synthesized in a chemistry laboratory also helped the modern chemistry to mature from its infancy.

Fields of specialization include biochemistry, nuclear chemistry, organic chemistry, inorganic chemistry, polymer chemistry, analytical chemistry, theoretical chemistry, quantum chemistry, environmental chemistry, and physical chemistry.

Biochemistry and organic chemistry are closely related, for example, in medicinal chemistry.

The distinction between organic and inorganic disciplines is not absolute and there is much overlap, most importantly in the sub-discipline of organometallic chemistry.

* Organic chemistry is the study of the structure, properties, composition, mechanisms, and chemical reaction of organic compounds.

* Cracking ( chemistry ), the decomposition of complex organic molecules into smaller ones

In organic chemistry a carbonate can also refer to a functional group within a larger molecule that contains a carbon atom bound to three oxygen atoms, one of which is double bonded.

Substance Z, an active urinary peptide, was purified by extraction in organic solvents and repeated column chromatography ; ;

Short proteins can also be synthesized chemically by a family of methods known as peptide synthesis, which rely on organic synthesis techniques such as chemical ligation to produce peptides in high yield.

Wieland's work led to the ' active ester ' method for making protected peptide segments in conventional solution synthesis in organic solvents.

Diketopiperazines ( DKP ) are a class of cyclic organic compounds that result from peptide bonds between two amino acids to form a lactam.

In organic solvents and crystals this peptide forms different types of non-native double helices.

Many laboratory methods exist for the organic synthesis of arenes from non-arene precursors.

As late as the 1840s, and despite Friedrich Wöhler's synthesis of urea in 1828, some chemists still believed in the doctrine of vitalism, according to which a special life-force was necessary to create organic compounds.

Boron-containing reagents are used for as intermediates in the synthesis of organic fine chemicals.

Then, in 1828, Friedrich Wöhler published a paper on the synthesis of urea, proving that organic compounds can be created artificially.

Small molecules are typically manufactured through traditional organic synthesis, and many can be taken orally.

Many catalytic processes, especially those used in organic synthesis, require so called " late transition metals ", which include palladium, platinum, gold, ruthenium, rhodium, and iridium.

Other chemists who brought major contributions to organic chemistry include Alexander William Williamson with his synthesis of ethers and Christopher Kelk Ingold, who, among many discoveries, established the mechanisms of substitution reactions.

Wöhler is regarded as a pioneer in organic chemistry as a result of his ( accidentally ) synthesizing urea in the Wöhler synthesis in 1828.

The functional group added can be subjected to ordinary synthesis methods to attach virtually any kind of organic compound onto the surface.

One cannot overstate its centrality in all chemistry, especially because of its necessary targeting in organic synthesis, and its roles in enzyme catalysis and inhibition, and in the formation of biological structures, both via its hydrogen bonding capability.

Ethyl acetoacetate, a very important starting material in organic synthesis, can be prepared using a diketene in reaction with ethanol.

As a composer, Hartmann attempted a difficult synthesis of many different idioms, including musical Expressionism and jazz stylization, into organic symphonic forms in the tradition of Bruckner and Mahler.

The smallest molecule is the diatomic hydrogen ( H < sub > 2 </ sub >), with a bond length of 0. 74 Å. Molecules commonly used as building blocks for organic synthesis have a dimension of a few Å to several dozen Å.

The resulting carbanions are key intermediates in many reactions in organic synthesis and biosynthesis.

In 1828 Friedrich Wöhler produced the organic chemical urea ( carbamide ), a constituent of urine, from the inorganic ammonium cyanate NH < sub > 4 </ sub > CNO, in what is now called the Wöhler synthesis.

Beginning in the 20th century, progress of organic chemistry allowed the synthesis of highly complex molecules via multistep procedures.

In organic synthesis, sodium is used in various reactions such as the Birch reduction, and the sodium fusion test is conducted to qualitatively analyse compounds.

The electrical properties can be fine-tuned using the methods of organic synthesis and by advanced dispersion techniques.

Common uses for organic solvents are in dry cleaning ( e. g., tetrachloroethylene ), as paint thinners ( e. g., toluene, turpentine ), as nail polish removers and glue solvents ( acetone, methyl acetate, ethyl acetate ), in spot removers ( e. g., hexane, petrol ether ), in detergents ( citrus terpenes ), in perfumes ( ethanol ), nail polish and in chemical synthesis.

Already as an undergraduate, he did his first publishable research: on the synthesis of organic chlorides.

Many specialized methods have been developed for forming disulfides, usually for applications in organic synthesis.
