Q: Is polyethylene a derivative of hydrocarbons?: The definition is yes

Q: Artemisinin is not a derivative of hydrocarbons: Artemisinin is a colorless needle-like crystal obtained from the compound inflorescences Artemisia annua L., which is (3R, 5aS, 6R, 8aS, 9R, 12S, 12aR ) - octahydro-3,6,9-trimethyl-3,12-oxo-12H-pyran [4,3-j] -1,2-benzodiazepine-10 (3H) -one. Molecular formula for the C15H22O5.

Q: What is the most primitive person on earth?: In the 4 billion years ago, the Earth's water environment, the atomic group into molecules, the formation of a new four-balance body, and the Earth in the formation process, has gathered a lot of interstellar organic molecules, these molecules combined into macromolecules, Of the gravitational field and the anti-gravitational field to find the appropriate combination of objects. Macromolecules, molecules and atoms are also dependent on the formation of the force field to find the appropriate combination of objects, the formation of a new complex four-force balance body, where the gravitational field to play a long-range attraction (5-20 atomic diameter), which It also limits the macromolecules to obtain the desired combination of objects on a large scale, so macromolecules are combined into a moving tissue form, the most primitive marine microorganism. The macromolecules that move can mainly use the method of orienting the electromagnetic force to gradually develop into the original tissue that can swim in the water, so they can obtain a large amount of food (four-force balance) and accumulate some molecules in the body , These molecules in the original microbial parent force field guidance, combined with the mother similar to the new micro-organisms, these primitive microorganisms is essentially a complex macromolecule formation of the four balance body, which is the prototype of biological gene replication.

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: The aromatic hydrocarbon derivative refers to monocyclic or polycyclic: To see what is the derivative of aromatic hydrocarbons, by its own is a single ring or multi-ring decision

Q: What is organic matter? Candle is organic?: Candle chemical formula: C2H2 so candle is organic

Q: Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even: The number of hydrogen atoms in the hydrocarbon must be even.

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: Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.: Organic matter is an abbreviation for organic compounds. At present, human beings know more than 900 million kinds of organic matter, the number is far more than inorganic.

Q: Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not: As long as carbon and carbon double bonds and three hydrocarbons can be hydrocarbons
