Q: What is organic matter?: Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.

Q: Why the silicon hydride less, a lot of hydrocarbons. (Why did not you find silicon-based creatures) and why are so many oxides of silicon, little carbon oxides?: You know silane bar, SiH4, this thing will be spontaneous, very unstable

Q: What is the proportion of hydrocarbons synthesized by Fischer-Tropsch Synthese in liquid fuels consumed by Nazi Germany? What are the proportions of these hydrocarbons as an industrial raw material into their military industry, in addition to fuel? At that time, did the Fischer-Tropsch preparations occupy an important position in Nazi Germany's military industry or heavy industry?: The traditional FT synthesis method of the product of heavy hydrocarbon content is high, the composition is complex, so the combustion efficiency is not optimistic. Germany is in view of the supply of oil is less than consumption (loss of production areas and lack of refined production capacity) was forced to take the FT technology to add (Germany's local coal reserves larger). So the FT fuel in the World War II Germany's energy system accounted for little, the specific data is still controversial, there are 15% and 25% said.

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: Sodium can be used to identify derivatives of hydrocarbons: The alcohol reacts with sodium. (Such as phenolic C6H5OH, cresol CH3C6H4OH, etc.), carboxylic acids (such as formic acid HCOOH, acetic acid CH3COOH, etc.) (description: hydroxyl groups in the carboxylic acid are hydroxyl groups in the carboxyl group) and hydroxyl groups containing polyhydroxyaldehydes and polyhydroxy ketones Such as glucose, fructose, etc.)

Q: Is the system name of a hydrocarbon derivative named if the question can be named according to the nomenclature of the alkane?: No, aldehyde is functional group, must be aldehyde for the mother. In addition, when the aldehyde group is a substituent, it is named as a formyl group.

Q: Is steel not organic synthetic material?: Steel is a mixture, the vast majority of elemental iron, also contains other elements, carbon is mixed in the inside, and did not constitute a compound.

Q: Inorganic chemistry employment direction? Current research direction: Optical inorganic boring, and now are with rare earth elements and radioactive elements to do some material research. Or electrochemical. battery!

Q: What is the aromatic hydrocarbon .. what is the derivative of the aromatic hydrocarbon: Aromatic hydrocarbons referred to as "aromatic hydrocarbons", refers to the molecule containing benzene ring structure of the hydrocarbons. Is a closed chain.

Q: What is organic matter? Candle is organic?: Organic matter refers to the addition: carbon, carbon monoxide, carbon dioxide, carbonated and carbonate carbon compounds
