- Q: What is carbohydrate? What is organic? What is it?
- Most organic compounds mainly contain carbon, hydrogen two 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 one of the reasons for the many organic compounds. Organic compounds in addition to a few, can generally burn. Compared with inorganic matter, their thermal stability is relatively poor, the electrolyte is easy to heat decomposition. The melting point of organic matter is low, generally not more than 400 ℃. The polarity of organic matter is very weak, so most of the water is not soluble. The reaction between organic matter, mostly intermolecular reactions, often requires a certain activation energy, so the reaction is slow, often requiring catalyst and other means. And the reaction of organic matter is more complex, under the same conditions, a compound can often be several different reactions at the same time, generate different products.
- Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?
- Nitrogen derivatives are; dimethylamine;
- 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
- 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: Identification of Derivatives of Chemical Hydrocarbons in High School
- Derivatives have gone, and give a specific range Well
- Q: Will AsH3 (arsenic trioxide) is organic or inorganic
- So the organic matter must contain the element is the C element
- Q: Are hydrocarbons all organic?
- The organic matter is an abbreviation of an organic compound and refers to a compound containing a carbon (C) element (a carbon-containing oxide such as CO.CO2 and a carbonate and bicarbonate-containing compound such as CaCO3.NaHCO3, a metal carbide such as CaC2 , Cyanide, etc.), simply say that most of the carbon-containing compounds and their derivatives of all elements and their compounds, while carbonates, carbonates, bicarbonates and other compounds, although the hydrocarbon is inorganic.
- Q: Other corals are because the color of the corals show colorful, why only the red coral is the exception of it? did not find the reasons for the big god to explain
- Organic compounds, the general purpose of carbon compounds (carbon monoxide, carbon dioxide, carbonic acid, carbonate, metal carbide, cyanide excluded) or hydrocarbons and their derivatives.
- 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: Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.
- Organic matter is an abbreviation for organic compounds. At present, human beings know more than 900 million kinds of organic matter, the number is far more than inorganic.
