Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, composition, reactions, and preparation ( by synthesis or by other means ) of carbon-based compounds, hydrocarbons, and their derivatives.

Organic synthesis of a novel compound is a problem solving task, where a synthesis is designed for a target molecule by selecting optimal reactions from optimal starting materials.

As much as The Picturesque was meant to be a middle ground or synthesis of the Beautiful and the Sublime for Price, for Townscape theorists, the Townscape movement was meant to be a middle ground or alternative approach to what were perceived by Hastings as two branches of Functionalism, the Rational ( i. e. Le Corbusier ) and the Organic ( i. e. Frank Lloyd Wright ) approaches to architecture and urban design.

Organic synthesis is a special branch of chemical synthesis and is concerned with the construction of organic compounds via organic reactions.

Organic molecules can often contain a higher level of complexity compared to purely inorganic compounds, so the synthesis of organic compounds has developed into one of the most important branches of organic chemistry.

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

Organic chemistry is the science concerned with all aspects of organic compounds.

The Protocol to the 1979 Convention on Long-Range Transboundary Air Pollution on Persistent Organic Pollutants is an agreement to provide for the control and reduction of emissions of persistent organic pollutants ( POPs ) in order to reduce their transboundary fluxes so as to protect human health and the environment from adverse effects.

The Stockholm Convention on Persistent Organic Pollutants, which entered into force in 2004, is an international legally binding agreement for the control of persistent organic pollutants.

Organic semiconductors, that is, organic materials with properties resembling conventional semiconductors, are also known.

Other haloalkanes, such as the hydrochlorofluorocarbon 1, 1-dichloro-1-fluoroethane ( HCFC-141b ), were used as interim replacements until their phase out under the Integrated Pollution Prevention and Control ( IPPC ) directive on greenhouse gases in 1994 and by the Volatile Organic Compounds ( VOC ) directive of the EU in 1997 ( See: Haloalkanes ).

Organic acids are used in food preservation because of their effects on bacteria.

Organic acids added to feeds should be protected to avoid their dissociation in the crop and in the intestine ( high pH segments ) and reach far into the gastrointestinal tract, where the bulk of the bacteria population is located.

Organic nutrients include carbohydrates, fats, proteins ( or their building blocks, amino acids ), and vitamins.

Due to the toxicity of PCBs and their classification as persistent organic pollutants, PCB production was banned by the U. S. Congress in 1977 and by the Stockholm Convention on Persistent Organic Pollutants in 2001.

Their fourth LP, 1992's " Organic " saw them move away from their traditional keyboard and acoustic guitar sound and use electric guitars for the first time, a change inspired by Davies ' new found love of indie music.

They are finding increasing acceptance and are preferred over solvent-based products in these applications as a result of their eco-friendly characteristics due to the absence of VOCs ( Volatile Organic Compounds ) in them.

While struggling with his incestuous feelings for his sister, he learns that he is the reincarnation of Organic Angel Alexiel, who led a rebellion against her fellow angels after witnessing their slaughter of the Evils, a group of demons, after God's disappearance.
