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:Calcium fatty acid is an organic or inorganic chemical: Fatty acid calcium is an organic chemical

Q:Alcohols and carboxylic acids in the hydroxyl group, the oxygen atoms are sp3 hybrid or sp2 hybrid: Are sp3 hybrid.

Q:The nature and use of cellulose derivatives: By replacing the reagent selection and process design, the product can be dissolved in water, dilute alkali solution or organic solvent, or have thermoplastic properties such as chemical fiber, film, film, plastic, insulating material, coating, slurry , Polymeric dispersants, food additives and household chemical products. The nature of the cellulose derivative and the nature of the substituent, the degree of substitution of the three hydroxyl groups on the glucose group, and the distribution of the substituents along the macromolecular chain. Due to the randomness of the reaction, the following three substitutions are different in other cases (homogeneous or heterogeneous reactions) except that the three hydroxyl groups are substituted (DS = 3) And non-substituted glucose groups: (1) monosubstituted (DS is 1, C, C or C position is substituted, the structural formula see cellulose); ② disubstituted (DS is 2, C, C, C, C Or C, C position is replaced); ③ total substitution (DS is 3). Thus, the properties of the same cellulose derivative having the same substitution value may also be quite different. For example, the cellulose diacetate which is directly esterified to DS of 2 is insoluble in acetone, but the cellulose diacetate obtained by saponification of the fully esterified cellulose triacetate can be completely dissolved in acetone. The irreducibility of this substitution is related to the basic rule of cellulose ester and etherification.

Q:Why not ah?: A series of compounds in which a hydrogen atom in a hydrocarbon molecule is replaced by another atom or radical is called a derivative of a hydrocarbon

Q:Is fatty acid and carboxylic acid the same thing?: In contrast, aromatic acids refer to carboxylic acids with benzene rings

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

Q:What are the sugar stocks?: ST Ganhua (000576): Jiangmen Sugarcane Chemical Plant (Group) Co., Ltd. formerly known as Jiangmen sugarcane chemical plant, founded in 1957.

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 difference between an aromatic compound and a hydrocarbon derivative?: The aromatic compound is a benzene ring containing compound, which may be a hydrocarbon or a hydrocarbon derivative. Hydrocarbons are hydrocarbon-containing compounds, and hydrocarbons containing hydrocarbons other than hydrocarbons are derivatives of hydrocarbons. The two concepts have crossed.
