Q: Simply talk about hydrocarbons: Hydrocarbon products in the daily production, life is widely used, the most representative of the commercial life of the HCR433b hydrocarbon refrigerant, and the most representative of the automotive HCR436a hydrocarbon refrigerant.

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

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: Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong: Organic compounds refer to hydrocarbons and their derivatives. Organic chemistry is the study of the structural characteristics of organic compounds, synthetic methods and physical and chemical properties of the chemical.

Q: Are hydrocarbons all organic?: A series of compounds with similar structures and different molecular composition of one or several "CH2" radicals are called the same series, and each member in the same series is called homologous, and the chemical properties of homologues are similar due to their similar structure. Their physical properties, often with the increase in molecular weight and regular changes.

Q: Inorganic chemistry employment direction? Current research direction: Optical inorganic boring, and now are with rare earth elements and radioactive elements to do some material research. Or electrochemical. battery!

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: Calcium coral is the main component of calcium carbonate, in addition to about 3% of magnesium carbonate and 1.5% to 4% of organic matter, and trace amounts of silicon and iron. The presence of organic matter increases the toughness of corals, making it better for processing and polishing. Calcium coral colors are mostly white or gray, but when it contains a considerable amount of different impurities, it is possible to show red, pink, orange, yellow, blue, purple and other colors. Therefore, by the living environment and many other factors, the same kind of coral can have different colors, and different types of corals and stars showing the same color. Red coral is really because of carotene.

Q: Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even: Other hydrocarbon derivatives are not necessarily, such as halogenated hydrocarbons containing odd halogen molecules, containing an odd number of N atoms containing C, H. O, N four elements of the compound, their number of hydrogen atoms are odd.

Q: Why can organic matter be unique in chemical substances? What is the nature of the C atom?: Carbon, and can be spun, sp2, sp3 hybrid, so CH, CC, CO, CN, C = C, C = O, C = N and other covalent bonds can be formed and the key size is moderate, So these keys can also be more easily broken and generate new compounds. For silicon, the type of hybrid is mainly sp3 (no O = Si = O this molecule exists), but the Si-O bond bond energy is greater than Si-C, Si-Si, Si-H, so these keys are It is easy to break to produce SiO2, so there is the most natural Si-O compounds, and this compound is very stable, difficult to break down or other reactions.
