Q:What is organic matter?
Organic compounds (organic compounds) mainly by the oxygen elements, hydrogen, carbon elements. Organic matter is the material basis for life. Fat, amino acids, protein, sugar, heme, chlorophyll, enzymes, hormones and so on. Biological metabolism and biological genetic phenomena, are related to the transformation of organic compounds. In addition, many substances closely related to human life, such as oil, natural gas, cotton, dyes, chemical fiber, natural and synthetic drugs, are organic compounds.
Q:1. What are liquid hydrocarbons?
Pentane, g, x, n, decane, to eleven to hexadecane are liquid hydrocarbons. Ethanol is not a hydrocarbon, it is aerobic. Polymeric material is a compound of relatively high molecular weight Composition of the material, there are many, such as rubber, plastic, fiber, paint
Q:The role of aromatic hydrocarbons
Two cases: First, the name of monocyclic aromatic hydrocarbons, usually benzene ring for the mother, alkyl as a substituent. Second, the structure is more complex aromatic hydrocarbons, usually based on the hydrocarbon base, benzene ring as a substituent. Xylene, 2-methyl-3-phenylpentane, diphenylmethane, etc. For the naming of multifunctional compounds, attention is given to the priority order of the functional groups. The priority is preceded by the parent, usually: cations, COOH SO2H, COOR, COCl, CONH2, CN, CHO, CO, OH, SH, NH2, alkynes, alkenes, ethers, X, NO2, etc. [2]
Q:What is a derivative of a hydrocarbon? What is an aromatic hydrocarbon derivative?
Hydrocarbon derivatives include derivatives of linear and aromatic hydrocarbons such as chloroethane bromopropane bromobenzene
Q:Why does the molecular atom compound do not belong to the life structure
Life structure is composed of CHO as the main element through the covalent bond of the combination of hydrocarbons and their derivatives, and you said the molecular atomic compounds are usually atomic or ionic bond
Q:Why is red coral red?
Organic compounds, the general purpose of carbon compounds (carbon monoxide, carbon dioxide, carbonic acid, carbonate, metal carbide, cyanide excluded) or hydrocarbons and their derivatives.
Q:What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?
Nitrogen derivatives are; dimethylamine;
Q:Identification of Derivatives of Chemical Hydrocarbons in High School
Phenol and ferric chloride reaction, aldehyde and copper hydroxide will produce brick red precipitation, and the formation of silver diamine hydroxide silver phase precipitation, and there are aldehydes in formic acid, an aldehyde corresponding to two silver Generation, and formaldehyde can be seen as there are two aldehyde groups, can be generated corresponding to the four silver quality.
Q:What is the definition of organic matter
Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
Q:What is the isomeric structure of oxygen-containing derivatives?
Play the Transformers. As long as the same molecular formula, you can group out how many different structures, there are a number of isomers.
