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?
Silicon oxide than carbon, because the outermost layer of silicon has three levels ah, (SiO, SiO2, Si2O6) silicon less organic matter, the front also said that the organic instability of silicon
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 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: Will AsH3 (arsenic trioxide) is organic or inorganic
So the organic matter must contain the element is the C element
Q: Is acrylamide an oxygen-containing derivative of hydrocarbons?
There are many kinds of oxygen-containing derivatives of alcohols which can be classified into alcohols, phenols, aldehydes, carboxylic acids and esters, etc. The nature of the oxygen-containing derivatives of hydrocarbons is determined by the functional groups, and the nature of the organic compounds can be used to synthesize the oxygen- There is no organic matter to meet our needs.
Q: Sodium can be used to identify derivatives of hydrocarbons
A compound in which a hydroxyl group is directly attached to a carbon atom in a hydrocarbon group or a benzene ring side chain is called an alcohol.
Q: Hazardous Chemicals Inorganic Classes, Organic Classes What does it mean?
Hazardous chemicals refer to highly toxic chemicals and other chemicals that are harmful to humans, facilities and the environment, which are toxic, corrosive, explosive, burning and burning. Including explosives, compressed and liquefied gases, flammable liquids, flammable solids, spontaneous combustion and wet flammable materials, oxidants and organic peroxides, toxic and corrosive substances, etc.
Q: What is the current status of carbon dioxide capture technology and how is it compared to plants that absorb carbon dioxide?
The principle is probably that the middle of the thing is the electrode, and then the surface of the electrode there are some powerful catalyst in the sunlight can promote the oxidation of water or carbon dioxide reduction. The electrode can move the proton to the other side and not allow the product or product to move to the other side. After the proton has been transferred, the electrochemical process can be used to hydrogenate the carbon dioxide.
Q: What is organic?
Human beings have a long history of organic compounds. As early as the 17th century, humans could only obtain some organic compounds such as protein, fat, carbohydrate and dyes from animals and plants as food, food and clothing. 1828 German chemist Wilhelm (F Wohler) for the first time with inorganic acid ammonium nitrate synthesis of organic urea. After 1844, people have synthesized a large number of organic compounds such as methane, acetylene, acetic acid, oil and sugar, and since then humans have made organic chemistry into the synthetic era. The development of synthetic organic matter is clearly recognized: there is no clear boundary between organic matter and inorganic matter, but there are some differences in composition, structure and nature. Now people already know that organic compounds in the composition of most contain carbon, hydrogen, oxygen, nitrogen and other elements, a few also contain sulfur, phosphorus, halogen and so on. Any organic compound, its molecular composition contains carbon, the vast majority also contains hydrogen. Since the hydrogen atoms of the organic compound molecules can be replaced by other atoms or radicals, so many other organic compounds are derived, it is generally believed that hydrocarbons and their derivatives are known as organic compounds, referred to as organic compounds; The chemistry of compounds is called organic chemistry.
Q: Carboxylic acid in the end can not react with the new copper hydroxide
But the formula is written in the carboxylic acid, because the reaction of aldehydes with the new copper hydroxide is alkaline conditions, the carboxylic acid is not present, but the carboxylic acid and alkali, copper hydroxide, copper oxide are reaction, Side reactions too much, too complex, in order to show that the reaction principle, simply from the simple processing, directly write carboxylic acid
