Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?: Oxygenated derivatives are: methyl ether, methyl ethyl ether, formaldehyde, ethylene oxide;

Q: Organic organic compounds are organic matter?: Organic polymer compounds are organic matter

Q: Is polyethylene a derivative of hydrocarbons?: No, the derivative of the hydrocarbon is an element other than c.H

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: The functional group of the derivative of the hydrocarbon: Common functional groups are: carbon-carbon double bond, -OH-COOH-CHO-NH2, often react, replace (including halogenation, nitration, sulfonation, esterification, hydrolysis, etc.), addition, elimination, addition polymerization , Organic matter oxidation and reduction, color and so on.

Q: Are all carbon compounds all organic?: Not organic matter that is organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonates, metal carbides and other rare carbon compounds excluded) or hydrocarbons and their derivatives in general. Organic matter is the material basis for life.

Q: What is the difference between organic matter and inorganic matter?: Inorganic matter is an inorganic compound. Generally refers to the elements other than carbon elements, such as water, salt, sulfuric acid, lime and so on. However, some simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides, because of their composition and properties and inorganic similar, so also as an inorganic to study. The vast majority of inorganic matter can be classified as oxides, acids, alkalis and salts.

Q: Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons: Pro-butylbenzene ethane

Q: Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?: Organic matter

Q: Such as the title, the personal feeling of chemical transliteration of Chinese transliteration can be done so easy to write, weird name in addition to keep the high point, no good, but rather affect the people's understanding of medicine and memory, contrary to the text to facilitate the exchange of memory Original intention: The title as a Chinese people are not proud of it Do not let you change the way back? Japanese back a element you a cycle almost finished finished ok Chinese can also sideways back to the back of foreign chemistry can cycle table How much is the back? Chinese people want to back half a day to solve the ok
