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: 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: 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: How to do it? Solve Inorganic Chemistry: Inorganic chemistry is one of the earliest disciplines in the development of chemical science. It undertakes a major task of studying the composition, structure, properties and reactions of all elements and elements (except hydrocarbons and derivatives). The current development of inorganic chemistry has two distinct trends, that is, in the breadth of the broadening and depth of the advance. It is the three pillars of modern civilization

Q: Sodium can be used to identify derivatives of hydrocarbons: The alcohol reacts with sodium. (Such as phenolic C6H5OH, cresol CH3C6H4OH, etc.), carboxylic acids (such as formic acid HCOOH, acetic acid CH3COOH, etc.) (description: hydroxyl groups in the carboxylic acid are hydroxyl groups in the carboxyl group) and hydroxyl groups containing polyhydroxyaldehydes and polyhydroxy ketones Such as glucose, fructose, etc.)

Q: Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong: Correct

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: 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: Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not: Should be able to ah and bromine water addition reaction and fade:
