- Q:Is steel not organic synthetic material?
- Steel is a mixture, the vast majority of elemental iron, also contains other elements, carbon is mixed in the inside, and did not constitute a compound.
- Q:Rush! Hydrocarbon and hydrocarbon derivatives system information includes chemical formula, common name, Chinese name and so on
- The system is too difficult to summarize. Too much.
- 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:What is organic matter? Candle is organic?
- Candle chemical formula: C2H2 so candle is organic
- Q:Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons
- Pro-butylbenzene ethane
- Q:What is the meaning of organic ah, organic food on the human body what practical benefits
- Fertilizer point of view, mainly organic fertilizer. Human synthesis of the first organic matter --- urea, but also organic matter. Organic manure is mainly manure and stool, straw straw and so on.
- Q:What is "organic" and "inorganic" in chemistry?
- Carbon-free substances or carbon oxides, carbonates, bicarbonates are organic matter
- 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:Simply talk about hydrocarbons
- Hydrocarbon is a hydrocarbon compound. The organic compound consisting only of carbon and hydrogen is called a hydrocarbon and a hydrocarbon, which reacts with chlorine, bromine vapor, oxygen, etc. to produce a hydrocarbon derivative, Hydrocarbons (and benzene) do not react with strong acids, strong bases, strong oxidants (eg potassium permanganate), but unsaturated hydrocarbons (olefins, alkynes, benzene homologues) can be oxidized or react with hydrogen halide The
- 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
