- 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: Organic organic compounds are organic matter?
- Organic polymer compounds are organic matter
- 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: Are there two derivatives of equivalent hydrogen?
- You give the scope is too broad, at least to set in what kind of functional group range ah.
- Q: Artemisinin is not a derivative of hydrocarbons
- There are many types of hydrocarbons, flammable and explosive materials, the structure of the known hydrocarbons in more than 2000. The hydrocarbon is the parent of the organic compound, and the other various organic compounds can be regarded as derivatives of one or more hydrogen atoms in the hydrocarbon molecule being replaced by atoms or radicals of other elements.
- 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: What is the definition of organic matter
- Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
- Q: What is the difference between hot and cold asphalt?
- Grandmother next door aunt is the street to sell stewed meat, a child often see her burning a pot of hot asphalt pork hair, black asphalt boiled immediately leaching in the meat, and so dry quickly pull it down, pork will Change very clean and white, clean the meat will be directly thrown into the pot halogen system, this method relative to the traditional plucking save time and effort a lot. Here, please bloggers blame me to come to funny, because the end of the story is not funny, that aunt's little sister in the sixth grade when suffering from leukemia away, adults say with her home burning asphalt There are relationships, eighteen years later, and she only a few side of the edge of the I actually remember the full name of her sister, her looks, the tone of her voice, we played the game and we were a very curious In the asphalt pot to see the scene of pig hair ... ... hope that each parents do not ignore the child's growth in the small problem.
- Q: High school chemistry: Is the esterification reaction of carboxylic acid and alcohol a polymerization reaction?
- No, the polymerization reaction is the reaction of the polymer, the esterification reaction is the reaction of the formation of small molecules
- Q: What kind of carbohydrates?
- carbohydrate: common with sucrose, maltose, lactose in the diet mainly in the form of starch, dextrin and glycogen in the form of sugar in the two sugar from a molecule of glucose and a molecule of fructose Is the most commonly used additive in sweets, pastries and beverages, and sucrose is essentially free of other nutrients in addition to the supply of maltose, which consists of two molecules of fructose, consisting of one molecule of glucose and one molecule of galactose.
