Method for the classification of chemistry organic compounds

Feb 23, 2016

 In the narrow sense,chemistry organic compounds are mainly composed of carbon and hydrogen elements,they are compound which must contain carbon,but they do not include the carbon oxides (carbon monoxide, carbon dioxide, carbonate, carbonates, cyanides, thiocyanate, cyanate, metal carbides, some simple carbon compounds (such as SiC) - containing substances.But in a broad sense,chemistry organic compounds can not contain carbon.Organic matter is the material base of life, and all the living organisms are hemistry organic compounds.Fats, amino acids, proteins, sugars, heme, chlorophyll, enzymes, hormones, etc.. In vivo metabolism and biological genetic phenomena, are related to the transformation of organic compounds. In addition, many human life is closely related to the material, such as oil, natural gas, cotton, dyestuff, chemical fiber, plastics, organic glass, natural and synthetic drugs, and organic compounds has a close contact.

   Chemistry organic compounds are carbon containing compounds or hydrocarbons and their derivatives. Chemistry organic compounds are the material basis of life.In addition to carbon,chemistry organic compounds may also contain hydrogen, oxygen, nitrogen, chlorine, phosphorus and sulfur and other elements.

   In short,chemistry organic compounds are carbon containing compounds, but the carbon containing compounds are not necessarily chemistry organic compounds.

   Method for the classification of chemistry organic compounds:

   The types of chemistry organic compounds are various, they can be divided into two types of hydrocarbon and hydrocarbon derivatives.According to the carbon structure of organic molecules, they can be divided into three kinds of open chain compounds, carbon ring compounds and heterocyclic compounds. According to the different functional groups contained in organic compounds, and they are divided for alkanes, alkenes, alkynes, aromatic hydrocarbons and halogenated hydrocarbons, alcohols, phenols, ether, aldehyde, ketone, carboxylic acid, ester and so on.

   Class heterogeneity:

   Chemistry organic compounds have the following categories of heterogeneous relationships:

   1 molecules with CnH2n (n = 3) categories: isomers of olefins and naphthenes;

2 molecules with CnH2n-2 (n = 4) categories: isomers of alkynes and dienes;

3 molecules with CnH2n+2O (n = 3) categories: isomers of saturated monobasic alcohol and saturated ether;

4 molecules with CnH2nO (n = 3) categories: isomers of saturated monobasic saturated aldehyde and ketone element;

5 molecules with CnH2nO2 (n = 2) categories of isomers: saturated carboxylic acid and saturated monobasic ester;

6 molecules with CnH2n-6O (n = 7) categories: phenol homologues isomers, aromatic alcohols and aromatic ether;

Such as n=7, there are five kinds of: O, P, P, P, P, benzyl alcohol, benzyl ether.

7 molecules with CnH2n+2O2N (n = 2) categories: amino acid and isomers of nitro compounds
