- Q:Simply talk about hydrocarbons
- Hydrocarbons in petroleum are abbreviations of hydrocarbons, which are written in the "water" and "water" in "carbon". Hydrocarbons are classified as saturated hydrocarbons and unsaturated hydrocarbons. Petroleum hydrocarbons are mostly saturated hydrocarbons, and unsaturated hydrocarbons such as ethylene, acetylene, etc., generally only in the oil processing process can be obtained.
- Q:The role of aromatic hydrocarbons
- Two cases: First, the name of monocyclic aromatic hydrocarbons, usually benzene ring for the mother, alkyl as a substituent. Second, the structure is more complex aromatic hydrocarbons, usually based on the hydrocarbon base, benzene ring as a substituent. Xylene, 2-methyl-3-phenylpentane, diphenylmethane, etc. For the naming of multifunctional compounds, attention is given to the priority order of the functional groups. The priority is preceded by the parent, usually: cations, COOH SO2H, COOR, COCl, CONH2, CN, CHO, CO, OH, SH, NH2, alkynes, alkenes, ethers, X, NO2, etc. [2]
- Q:Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons
- Pro-butylbenzene ethane
- Q:From the molecular level, are not all the energy obtained from the redox reaction?
- The battery is carrying the oxidant, and the hydrocarbon is the air as an oxidant direct reaction, which is less than the rocket engine than the jet engine than the reasons for the red.
- 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
- 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:Is acrylamide an oxygen-containing derivative of hydrocarbons?
- From the structural point of view, alcohol, vinegar, malic acid, citric acid and other organic matter, can be seen as hydrocarbon molecules in the hydrogen atoms are replaced by oxygen atoms and atomic groups, they are known as hydrocarbon oxygen derivatives.
- Q:What is the proportion of hydrocarbons synthesized by Fischer-Tropsch Synthese in liquid fuels consumed by Nazi Germany? What are the proportions of these hydrocarbons as an industrial raw material into their military industry, in addition to fuel? At that time, did the Fischer-Tropsch preparations occupy an important position in Nazi Germany's military industry or heavy industry?
- Now, the improved economic benefits of FT still limit its further development. Some of the enterprises' coal indirect liquefaction projects have been terminated (for example, Shenhua Group), coupled with the impact of breakthrough development of shale oil technology, the development prospect of coal indirect liquefaction not optimistic.
- Q:What cells are composed of compounds
- The organic matter that constitutes the cell generally refers to the general term for carbon-containing compounds or hydrocarbons and their derivatives. In nature, the types of organic matter are extremely numerous. Among them, organic compounds - carbohydrates, proteins and nucleic acids, which are composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, are the most important organic compounds in cells.
- Q:Ionic compounds, covalent compounds, electrolytes, non-electrolytes, which are both compounds and inorganic compounds
- They are different concepts -
