term "organic material" appeared in the days when the chemistry is still in its infancy, in the eastern teachings, in the Aristotelian classicism, in the teachings of Hippocrates.Under the organic matter to be understood as belonging to the realm of plants and animals.Under inorganic substances - belonging to the realm of inanimate things.There was a strong belief that organic matter can not be created from inorganic, which, however, was refuted in the XIX century.

properties of organic compounds

organic compounds - the largest class of chemical compounds: Currently, they number a little less than 27 million (according to other sources - more than 30 million).The reason for such a large variety of them - the ability to create a chain of carbon atoms, and high sta
bility of the bonds between atoms in carbon bond.High carbon valency (IV) allows him to create stable compounds with other atoms.In this connection may not only once, but two, and three-time (ie, double and triple), which allows you to create a substance with linear, flat and three-dimensional structures.

organic substances are the basis of existence of living organisms that are the basis of human food, animals and plants are widely used as raw materials for many industries.

In geology under the organic substances are understood compounds, directly or indirectly arising out of a living organism, from the products of his life.They are an essential component in the water, the atmosphere, sediments, soils and rocks.They may also be in solid, liquid and gaseous states.

Classification of organic compounds

Inside organic compounds has its own, internal classification.Classical organic compounds are considered proteins, lipids, nucleic acids and carbohydrates.Their distinguishing characteristic is the presence of nitrogen, oxygen, hydrogen, sulfur, and phosphorus.Individual classes - organic and organometallic compounds.The first is a carbon compound with elements not listed above.Second - carbon compounds with metals.

Organic Chemistry Organic Chemistry - Chemistry Section studying organic compounds, their structure and properties, the technology of their synthesis.Until the 70s of XX century leader in the field of research of organic matter was Germany.Moreover, organic chemistry was considered a purely German science and still German chemical terminology adopted in many developed countries.
