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: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: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:What is the current status of carbon dioxide capture technology and how is it compared to plants that absorb carbon dioxide?

Landlord can check their own literature what. = For example, I think this review is very good. The Although it does not include relatively new progress, but I think it is quite good. The You see such an answer to the efficiency of how low ah not as good as their own to find the literature to see right

Q:NH4HCO3 and so have C atoms ah, why still inorganic

Organic definition is not all elements, if only look at carbon atoms, then graphite and carbon dioxide are also areas of organic matter, so this is not the case. In general, organic matter is defined as containing atomic elements, which can be combusted, low density, low melting point, strong volatility, poor solubility in water, etc., which are composed of carbon atoms and covalent bonds.

Q:What is the difference between organic matter and inorganic matter?

Organic matter that organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonates, metal carbides and other rare carbon compounds excluded) or hydrocarbons and their derivatives in general. Organic matter is the material basis for life.

Q:What is "organic" and "inorganic" in chemistry?

Carbon-free substances or carbon oxides, carbonates, bicarbonates are organic matter

Q:Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.

2. Previously, the known organic matter is obtained from animals and plants and other organisms, so this kind of compound is called organic matter. To the 1820s, scientists have used inorganic synthesis of many organic compounds, such as urea, acetic acid, fat, etc., to break the organic matter can only be obtained from the organic concept. However, due to historical and customary reasons, people still use the name of organic matter.

Q:China's largest asphalt production base where

Coal tar pitch is a byproduct of coking, that is, the black material that remains in the distillation kettle after distillation of the tar. It is only fine with the physical properties of refined tar, there is no obvious boundaries, the general division method is to specify the softening point at 26.7 ℃ (cubic method) for the following tar, 26.7 ℃ above the asphalt. Coal tar pitch mainly contains volatile anthracene, phenanthrene, pyrene and so on. These substances are toxic, because the content of these components are different, the nature of coal tar pitch is also different. The change of temperature has great influence on coal tar pitch, which is easy to brittle in winter and easy to soften in summer. Heating with a special smell; heated to 260 ℃ in 5 hours later, it contains anthracene, phenanthrene, pyrene and other ingredients will be volatile.

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
