- Q: Why does the molecular atom compound do not belong to the life structure
- Life structure is composed of CHO as the main element through the covalent bond of the combination of hydrocarbons and their derivatives, and you said the molecular atomic compounds are usually atomic or ionic bond
- Q: What is cigarization?
- Many people have a serious alcoholic misunderstanding that the longer the better alcoholization time, this is a beautiful misunderstanding, each cigar unique alcohol cycle is a lifelong pursuit of the mystery. For Cuban cigars, some support for 10 years after 8 years, you will be pleasantly surprised to find the cigar reached round mellow and, for example, Patagas, but some of the ten years will taste like chewing wax, cigars tend to death almost no taste.
- Q: What are the derivatives of hydrocarbons?
- In addition to the C and H elements, there are also one or more of O, X (halogen), N, S and other elements, such as methanol (CH3OH) learned from junior high school chemistry, (CH3Cl), nitrobenzene (C6H5NO2), and the like, which are mentioned in the previous chapter, are derivatives of hydrocarbons, such as ethanol (C2H5OH), acetic acid (CH3COOH)
- Q: What is the difference between organic matter and inorganic matter?
- Organic matter that 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: Carboxylic acid and alcohol can react, is it necessary to have certain conditions, if the conditions can not reach, is not it can not respond?
- This is not you know the wine wine fruit flavor from ethyl acetate it is ethanol and acetic acid esterification out of the esterification of the esterification reaction needs to concentrate sulfuric acid catalysis that is because the laboratory to yield to the speed So it is necessary to reduce the activation energy to try their esterification but miscible case will react but very very slow wine more Chen Yue Hong to wait ten years or even hundreds of you will not be willing to do so
- Q: Why not ah?
- A series of compounds in which a hydrogen atom in a hydrocarbon molecule is replaced by another atom or radical is called a derivative of a hydrocarbon
- Q: How to distinguish between inorganic chemicals and organic chemicals
- Hydrocarbons and their derivatives are organic chemicals. There are carbon and hydrogen compounds, in addition to carbonic acid series, cyanide series of things, carbon oxides, the rest you can think of are organic compounds, these compounds as the main ingredient of the chemical is organic chemicals. Inorganic chemistry focuses on the study of the structure and properties of inorganic matter and its use, and is devoted to the study of organic matter (carbon) in all aspects of knowledge. Inorganic and life closer, organic and industrial and agricultural production more closely.
- Q: Why artemisinin and its derivatives in the molecular structure of a peroxide chain, the chemical properties are more stable?
- Artemisinin is relatively stable, is relative to other organic peroxide in terms of, in general, most of the organic peroxide instability, heating easily decomposed, and some even easy to burn the explosion, such as dibenzoyl peroxide, but crystal cyan Artemisinin heating to the melting point does not break down, has been considered stable.
- Q: How the most primitive life on earth is produced under what conditions
- The most primitive creatures on earth are actually RNA, which is pulled earlier than any prokaryotic cells, and the eukaryotic cells are advanced, in short, the chemical reaction in the environment at that time.
- Q: What are the sugars?
- Carbohydrate carbohydrates, also known as carbohydrates, are the most widely distributed and most important organic compounds in the world. Glucose, sucrose, starch and cellulose are all carbohydrates. X0d carbohydrates are all organisms The main source of energy needed to sustain life activities is not only nutritious but also has special physiological activity, such as: heparin in the liver has anticoagulant effect; blood sugar in the blood type related to immune activity.In addition, the nucleic acid The carbohydrate compounds are more important for medicine, and the carbohydrate compounds are composed of three elements, C, H and O, And O is usually 2: 1, and the proportion of water molecules, which can be expressed by the general formula Cm (H2o) n.Therefore, these compounds have been called carbohydrates, but later found that some compounds according to their structure and (C6H12O5), deoxyribose (C5H10O4), etc .; and some compounds such as acetic acid (C2H4O2), lactic acid (C3H6O3), and other compounds, such as acetic acid (C2H4O2), lactic acid (C3H6O3) And its composition is consistent with the general formula Cm (H2o) n, but the structure and properties are completely different with the carbohydrate compounds, so the name of the carbohydrate is not exact, but for a long time, so far still in use. X0d from Chemical structures, carbohydrates are polyhydroxyaldehydes, polyhydroxy ketones, and their condensates. <X0d sugars can be divided into three categories according to the hydrolysis and hydrolysis products: x0d monosaccharides: polyhydroxyalides that can not be hydrolyzed Such as glucose, fructose, etc. x0d disaccharides: hydrolysis of sugar to produce two molecules of monosaccharides such as sucrose, maltose, etc. x0d polysaccharide: can be hydrolyzed to produce many molecules of sugar monosaccharides such as starch, glycogen, Cellulose, etc. x0d sugars often use their names according to their origin.
