Q: What does organic and inorganic mean?: Organic and inorganic machine myself ~ female and male

Q: Simply talk about hydrocarbons: Hydrocarbons in petroleum are abbreviations of hydrocarbons, which are written in the "water" and "water" in "carbon". Hydrocarbons are classified as saturated hydrocarbons and unsaturated hydrocarbons. Petroleum hydrocarbons are mostly saturated hydrocarbons, and unsaturated hydrocarbons such as ethylene, acetylene, etc., generally only in the oil processing process can be obtained.

Q: Why does toluene not belong to the derivatives of hydrocarbons?: Hydrocarbon: sound tīng, is composed of two elements of carbon and hydrogen organic compounds known as hydrocarbons, also known as hydrocarbons. It reacts with chlorine, bromine, oxygen and other hydrocarbons to produce derivatives of hydrocarbons. Such as methane and chlorine in the light conditions of reaction to produce methyl chloride, dichloromethane, chloroform and chloroform (carbon tetrachloride) and other derivatives. The concept of derivatives is hydrocarbon and chlorine, bromine, oxygen and other reaction products. While toluene is not methyl and benzene, she is a whole noun is aromatic. Also known as aromatic hydrocarbons. Generally have one or more six-ring (benzene ring) with a special structure. The simplest aromatic hydrocarbons are benzene, toluene, xylene. There is also naphthenes. As the name suggests it is a ring structure. The most common is the five carbon atoms or six carbon atoms of the ring, the former called cyclopentane, which is called cyclohexane. The molecular formula of the cycloalkane is of the formula CnH2n. Cycloalkane is also called cycloalkane hydrocarbons. And alkanes. Is a carbon atom between the single bond phase chain hydrocarbon. Since the number of atoms that make up the hydrocarbon and hydrogen is different, the result is that the petroleum contains hydrocarbon molecules with large and small differences. Alkanes are named according to the carbon atoms and numbers contained in the molecule, and the number of carbon atoms is less than 10, from 1 to 10, followed by a, B, C, D, E, G, Alkane to say that the number of carbon atoms in more than 11, with the number that thank you to adopt

Q: High school chemical hydrocarbons with hydrocarbon derivatives with water solubility, density for accurate and comprehensive summary, thank you. Out of college entrance examination: Hydrocarbons are insoluble in water and have a lower density than water

Q: What are the inorganic compounds: Hydrocarbons and their derivatives.

Q: Sodium can be used to identify derivatives of hydrocarbons: A compound in which a hydroxyl group is directly attached to a carbon atom in a hydrocarbon group or a benzene ring side chain is called an alcohol.

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: Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?: The heterocyclic compound is an organic compound containing a heterocyclic structure in its molecule. The atoms that make up the ring contain at least one heteroatom in addition to carbon atoms. The heteroatoms include oxygen, sulfur, nitrogen and the like. Theoretically, the heterocyclic compound can be regarded as a derivative of benzene, that is, one or more CH in the benzene ring is replaced by a heteroatom. The heterocyclic compound may be in parallel with the benzene ring to form a fused ring heterocyclic compound.

Q: Why can organic matter be unique in chemical substances? What is the nature of the C atom?: To give a reason, the current production of more economical temperature control is limited.

Q: Why artemisinin and its derivatives in the molecular structure of a peroxide chain, the chemical properties are more stable?: Heated to more than sixty degrees on the decomposition of things how to say that stability ...
