- 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: 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: Why is dry ice not organic?
- Inorganic compounds are pure metals that do not contain carbon and a collection of simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides.
- Q: What are the derivatives of hydrocarbons?
- Including alcohols, acids, aldehydes, ethers, esters, halogenated hydrocarbons and the like
- 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: Is the system name of a hydrocarbon derivative named if the question can be named according to the nomenclature of the alkane?
- Halogen can be named after the alkane, the other can not
- Q: Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?
- The heterocyclic compound is an organic compound containing a heterocyclic structure in its molecule. The atoms that make up the ring contain at least one heteroatom in addition to carbon atoms. The heteroatoms include oxygen, sulfur, nitrogen and the like. Theoretically, the heterocyclic compound can be regarded as a derivative of benzene, that is, one or more CH in the benzene ring is replaced by a heteroatom. The heterocyclic compound may be in parallel with the benzene ring to form a fused ring heterocyclic compound.
- Q: What is organic?
- Simply refers to the organic ingredients containing organic ingredients. The real organic cosmetics are organic plants as the main raw material, do not add artificial spices, artificial colors, oil-free ingredients, the added preservatives and surfactants must be strictly limited, and the manufacturing process to comply with the relevant provisions, can not use animals Experiments and the use of radiation sterilization products. In general, the certification of organic skin care products must meet the following conditions: First, the organic environment, the closest growth of natural growth, production base (ie, the environment) are not damaged, water (irrigation water), soil (soil ), Gas (air) is not contaminated. Second, organic cultivation, no artificial fertilizer irrigation or artificial feed, without antibiotics, chemical insecticide, without genetic variants. Third, the organic processing and production projects, including the harvest after washing, finishing, packaging, processing, transportation, storage, sales and other sectors) did not subject to secondary pollution.
- Q: Rush! Hydrocarbon and hydrocarbon derivatives system information includes chemical formula, common name, Chinese name and so on
- hydrocarbon
- 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
- China's chemical name may be the best of both Latin and English
