Q:What is the organic compound in high school chemistry?
Not without hydrogen, there must be C, but the material containing C is incomplete organic matter. Like H2CO3 and carbonate
Q:The problem of system naming of hydrocarbon derivatives
Halogen can be named after the alkane, the other can not
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: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:Identification of Derivatives of Chemical Hydrocarbons in High School
Phenol and ferric chloride reaction, aldehyde and copper hydroxide will produce brick red precipitation, and the formation of silver diamine hydroxide silver phase precipitation, and there are aldehydes in formic acid, an aldehyde corresponding to two silver Generation, and formaldehyde can be seen as there are two aldehyde groups, can be generated corresponding to the four silver quality.
Q:Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong
Organic compounds refer to hydrocarbons and their derivatives. Organic chemistry is the study of the structural characteristics of organic compounds, synthetic methods and physical and chemical properties of the chemical.
Q:Are hydrocarbons all organic?
A series of compounds with similar structures and different molecular composition of one or several "CH2" radicals are called the same series, and each member in the same series is called homologous, and the chemical properties of homologues are similar due to their similar structure. Their physical properties, often with the increase in molecular weight and regular changes.
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:What is "organic" and "inorganic" in chemistry?
Inorganic compounds are inorganic compounds, usually refers to non-carbon compounds. , Alkali, salt and so on.
Q:Organic organic compounds are organic matter?
Organic matter is defined as the presence of hydrocarbons and their derivatives, and the presence of covalent bonds is a feature of them.
