- 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: Compare the difference between London smoke and Los Angeles photochemical smog
- Los Angeles photochemical smog nitrogen content and hydrocarbons and derivatives more, mainly close to the car exhaust. Foggy London situation related to coal, soot solid particles and sulfur oxide more. Foggy London is more bleak, and Los Angeles is more toxic.
- Q: Sugar, fat, and so on a variety of organic matter is full of different units of the heat of the small box. (Save the heat the most efficient, the least loss of heat the most practical and most economical box).
- The fundamental difference between organic matter and inorganic matter is whether it contains carbon elements (except carbon monoxide, carbon dioxide, carbonates, metal carbides and other simple carbon compounds). Is the carbon-based life (that is, we) the division of life material and non-life material academic concept. Regardless of whether or not to store heat. The ability of many inorganic materials to store heat is much higher than that of organic matter. From a broad cosmic perspective. Organic and inorganic division does not make sense, assuming that there is a silicon-based life (this possibility is very high). Then their organic and inorganic division should lie in whether it contains silicon.
- Q: Such as the problem, and how, how to squeeze methane into liquid, or how to squeeze into the liquid gas? It is still very difficult ... there is a dangerous thing .... (this is not important) high reward
- 1. A hydrocarbon containing five to eight carbons 2. Not, it is an oxygen-containing derivative of a hydrocarbon 3. A hydrocarbon and a halogenated hydrocarbon (unsaturated) polymer, an alcohol, a phenol and
- Q: Peracetic acid is not
- A series of compounds produced by the substitution of hydrogen atoms in other molecular or atomic groups as hydrocarbon derivatives, peroxyacetic acid is CH3COOOH, and should be considered
- Q: Inorganic chemistry employment direction? Current research direction
- Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic matter, which is the oldest branch of chemistry. Inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds. (In addition to carbon dioxide, carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.) Inorganic chemistry is in addition to hydrocarbons and their derivatives, the nature of all elements and their compounds And their reaction to experimental research and theoretical interpretation of science, is the development of the discipline of the earliest branch of a discipline.
- Q: Is grease a polymer compound? Is it a derivative of saturated hydrocarbons?
- Not a polymer can not be considered a saturated hydrocarbon derivatives. Natural oils contain unsaturated structures
- Q: Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?
- Organic matter
- Q: Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.
- 4. A wide variety of organic matter, hydrocarbons and hydrocarbons can be divided into two major categories of derivatives. According to the organic groups contained in the functional groups, divided into alkanes, alkenes, alkynes, aromatic hydrocarbons and alcohols, aldehydes, carboxylic acids, esters and so on. According to the organic carbon molecular structure, can also be divided into open chain compounds, carbocyclic compounds and heterocyclic compounds three categories.
- Q: Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not
- As long as carbon and carbon double bonds and three hydrocarbons can be hydrocarbons
