- Q: What is organic matter?
- Organic compounds (organic compounds) mainly by the oxygen elements, hydrogen, carbon elements. Organic matter is the material basis for life. Fat, amino acids, protein, sugar, heme, chlorophyll, enzymes, hormones and so on. Biological metabolism and biological genetic phenomena, are related to the transformation of organic compounds. In addition, many substances closely related to human life, such as oil, natural gas, cotton, dyes, chemical fiber, natural and synthetic drugs, are organic compounds.
- Q: High school chemical hydrocarbons with hydrocarbon derivatives with water solubility, density for accurate and comprehensive summary, thank you. Out of college entrance examination
- Hydrocarbons, halogenated hydrocarbons, esters are difficult to dissolve in water. Hydrocarbons, esters are denser than water, and the density of halogenated hydrocarbons is generally greater than that of water. Hydrocarbon derivatives containing hydroxyl, amino or aldehyde groups such as alcohols, phenols, aldehydes, carboxylic acids, sulfonic acids and amines are soluble in water, And the shorter the solubility of the carbon chain, the greater the solubility of the carbon chain increases, until the same number of carbon atoms and similar hydrocarbons.
- Q: Sugar, fat, and so on a variety of organic matter is full of different units of the heat of the small box. (Save the heat the most efficient, the least loss of heat the most practical and most economical box).
- Organic matter carries more richer and more easily utilized by creatures
- Q: Are all carbon compounds all organic?
- Of course not Like carbon monoxide is not friends ~ ~ ~ In general, organic matter will contain at least two elements of carbon and hydrogen, but carbon tetrachloride is an exception. Many of the concepts in chemistry, or else there is a special case, or that is limited, can only control the total but can not control the whole. It is very annoying thing oh ~ ~ ~
- Q: Such as the problem, and how, how to squeeze methane into liquid, or how to squeeze into the liquid gas? It is still very difficult ... there is a dangerous thing .... (this is not important) high reward
- (3) polyethylene (2) is not, is a hydrocarbon derivative, there are C, H, O elements (3) polyethylene material (polyethylene material non-stick pan) (4) oil and oil produced gasoline is liquid , The general organic polymer materials can be burned
- Q: Is steel not organic synthetic material?
- Organic compounds that are organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonic acid, carbonates, metal carbides, cyanide excluded) or hydrocarbons and their derivatives in general. Most of the combustion can produce carbon dioxide and water.
- Q: What are the characteristics of organic compounds?
- Organic compounds are usually referred to as carbon-containing compounds, or hydrocarbon-containing compounds and their derivatives are collectively referred to as organic matter. Organic compounds are generally insoluble in water and soluble in organic solvents with lower melting points. The vast majority of organic matter heat easily decomposed, easy to burn. The reaction of organic matter is generally slow and often accompanied by side effects, and there are many kinds of organic compounds, which can be divided into two major categories of hydrocarbon and hydrocarbon derivatives. According to the organic groups contained in the functional groups, divided into alkanes, alkenes, alkynes, aromatic hydrocarbons and alcohols, aldehydes, carboxylic acids, esters and so on. According to the organic carbon molecular structure, can also be divided into open chain compounds, carbocyclic compounds and heterocyclic compounds three categories.
- Q: NH4HCO3 and so have C atoms ah, why still inorganic
- Organic matter is a general term for carbon compounds (except carbon oxides, carbon dioxide, carbonates, carbonates, bicarbonates, metal carbides, cyanides, thiocyanides and other oxides) or hydrocarbons and their derivatives. Organic matter is the material basis for life. The inorganic compound usually refers to a compound containing no carbon element, but a few carbon-containing compounds such as carbon dioxide, carbonic acid, carbon monoxide, carbonate and the like do not have the properties of an organic substance, and therefore such substances are also inorganic.
- 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.
- 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.
