Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?: Hydrocarbon derivatives of oxygen in the standard conditions are gaseous formaldehyde.

Q: What is the difference between crude oil and asphalt?: Difference: Asphalt is composed of different molecular weight hydrocarbons and non-metallic derivatives of dark brown complex mixture, is a high viscosity organic liquid, was liquid, the surface was black, soluble in carbon disulfide. Asphalt is a waterproof moisture and corrosion of organic cementitious materials. Asphalt can be divided into coal tar pitch, petroleum asphalt and natural asphalt three: Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural asphalt is stored in the ground, and some of the formation of ore or in the crustal surface accumulation. Asphalt is mainly used for coatings, plastics, rubber and other industries and pavement and so on. Crude oil (44.27,0.27,0.61%) is the upstream raw material of asphalt, there is a strong correlation between the two prices. For the asphalt industry, the impact of the upstream industry is mainly reflected in the fluctuations in crude oil prices, crude oil processing capacity changes in oil asphalt production and product prices fluctuations. From the downstream demand point of view, asphalt products are mainly used in highways, municipal roads, bridges and airports and other places of the laying of which highway construction for the consumption of asphalt accounted for 82%. In the case of a certain capacity, the increase in downstream demand will further promote the growth of asphalt prices, on the contrary, will bring the price down.

Q: Are all carbon compounds all organic?: Of course not Like carbon monoxide is not friends ~ ~ ~ In general, organic matter will contain at least two elements of carbon and hydrogen, but carbon tetrachloride is an exception. Many of the concepts in chemistry, or else there is a special case, or that is limited, can only control the total but can not control the whole. It is very annoying thing oh ~ ~ ~

Q: Is not organic matter must not hydrogen ah?: Organic matter that organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonates, metal carbides, cyanide excluded) or hydrocarbons and their derivatives in general. Organic matter is the material basis for life. 【Features】 Most organic compounds mainly contain carbon and hydrogen 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 the cause of many organic compounds

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: 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: What cells are composed of compounds: Water, various inorganic salts, sugars (mainly glucose and sugar), nucleotides, amino acids, lipids

Q: Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?: Hydrocarbons and hydrocarbon derivatives

Q: Why artemisinin and its derivatives in the molecular structure of a peroxide chain, the chemical properties are more stable?: Artemisinin is relatively stable, is relative to other organic peroxide in terms of, in general, most of the organic peroxide instability, heating easily decomposed, and some even easy to burn the explosion, such as dibenzoyl peroxide, but crystal cyan Artemisinin heating to the melting point does not break down, has been considered stable.

Q: Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?: Hydroxyls are directly attached to charcoal and alcohols are derivatives of hydrocarbons.
