Q: What is carbohydrate? What is organic? What is it?: Most organic compounds mainly contain carbon, hydrogen two elements, in addition often contain oxygen, nitrogen, sulfur, halogen, phosphorus and so on. Part of the organic matter from the plant sector, but the vast majority of oil, natural gas, coal as raw materials, through artificial synthesis method. Compared with inorganic substances, the number of organic matter, up to several million kinds. The carbon atoms of the organic compound have a very strong ability to bind to each other to form a carbon or carbocyclic ring. The number of carbon atoms can be 1,2, it can be thousands, tens of thousands, many organic polymer compounds can even have hundreds of thousands of carbon atoms. In addition, the isotopic phenomenon of organic compounds is very common, which is one of the reasons for the many organic compounds. Organic compounds in addition to a few, can generally burn. Compared with inorganic matter, their thermal stability is relatively poor, the electrolyte is easy to heat decomposition. The melting point of organic matter is low, generally not more than 400 ℃. The polarity of organic matter is very weak, so most of the water is not soluble. The reaction between organic matter, mostly intermolecular reactions, often requires a certain activation energy, so the reaction is slow, often requiring catalyst and other means. And the reaction of organic matter is more complex, under the same conditions, a compound can often be several different reactions at the same time, generate different products.

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.

Q: Compare the difference between London smoke and Los Angeles photochemical smog: Los Angeles photochemical smog nitrogen content and hydrocarbons and derivatives more, mainly close to the car exhaust. Foggy London situation related to coal, soot solid particles and sulfur oxide more. Foggy London is more bleak, and Los Angeles is more toxic.

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 FT synthesis method is a coal liquefaction technique under an iron-based catalyst (conventional FT method is a cobalt-based catalyst). Mainly syngas (CO and H2-based) saturated alkylation technology.

Q: The role of aromatic hydrocarbons: Aromatic compounds, historically, refer to a class of aromatic scent made from plant gums, but most of the currently known aromatic compounds contain no fragrance, so the word aromatic has been lost [1] The aromatic compounds are the general term for the carbocyclic compounds and their derivatives that conform to the Hockel rules, and their molecules have closed cyclic conjugated systems in their molecules; Π electrons meet 4n + 2, and the height is delimited; the bond length is averaged.Therefore, the compounds have a high degree of unsaturation, but the properties are relatively stable, such as easy to replace, and difficult to add and oxidation. This part focuses on the structure, naming, chemical properties, localization effects and application of aromatics in organic synthesis. [2]

Q: What is the difference between organic matter and inorganic matter?: Inorganic matter is an inorganic compound. Generally refers to the elements other than carbon elements, such as water, salt, sulfuric acid, lime and so on. However, some simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides, because of their composition and properties and inorganic similar, so also as an inorganic to study. The vast majority of inorganic matter can be classified as oxides, acids, alkalis and salts.

Q: What is the current status of carbon dioxide capture technology and how is it compared to plants that absorb carbon dioxide?: I think it 's harder if the thing is to be industrialized. = Such as carbon dioxide hydrogenation into methane, after the methane transport or storage is also a relatively large problem bars And not to say that the hydrogenation of carbon dioxide into methane has been studied for a long time, but it does not seem to have developed any big news like ah There is also electrochemical reduction of carbon dioxide. It is relatively easy to produce formic acid in the aqueous phase, such as the Partially oxidized atomic cobalt oxide for carbon dioxide electroreduction to liquid fuel (Nature: Nature Publishing Group) recently made by Xie Yi. The But the separation of formic acid and water is also a more difficult thing ah. The

Q: Inorganic chemistry employment direction? Current research direction: Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic matter, which is the oldest branch of chemistry. Inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds. (In addition to carbon dioxide, carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.)

Q: NH4HCO3 and so have C atoms ah, why still inorganic: Not all carbon compounds are organic compounds, CO, CO2, carbonic acid, carbonates (including salt and acid salts), metal carbides, cyanides, thiocyanates are inorganic compounds.
