- Q: What is organic matter?
- Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as 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
- The amount of forgotten, just remember the carbon six rings
- Q: Are the asphalt and peat kinds of vegetables have heavy metal?
- Asphalt is composed of different molecular weight hydrocarbons and non-metallic derivatives of dark brown complex mixture, is a high viscosity organic liquid, was liquid, the surface was black, soluble in carbon disulfide. Asphalt is a waterproof moisture and corrosion of organic cementitious materials. Asphalt can be divided into coal tar pitch, petroleum asphalt and natural asphalt three: Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural asphalt is stored in the ground, and some of the formation of ore or in the crustal surface accumulation. Asphalt is mainly used for coatings, plastics, rubber and other industries and pavement and so on.
- Q: Are there two derivatives of equivalent hydrogen?
- You give the scope is too broad, at least to set in what kind of functional group range ah.
- Q: Hydrocarbons and hydrocarbon derivatives are not all non-electrolytes
- Hydrocarbons are, derivatives are not necessarily, such as organic acids (formic acid, acetic acid, etc.)
- Q: What are the inorganic compounds
- The precise organics are defined as: hydrocarbons and their derivatives. The derivative is the product of the hydrogen atom H being replaced by other radicals
- Q: Why can organic matter be unique in chemical substances? What is the nature of the C atom?
- Organic this historical term, can be choked to the 19th century, when the students that organic compounds can only be biological (life-force, vis vitalis) synthesis. This theory is based on organic matter and "inorganic" the basic difference, organic matter can not be non-vitality synthesis. But later this theory was overthrown, the German chemist Friedrich W?hler to cyanide and ammonia synthesis of urea (inorganic synthesis of organic matter). In general, organic compounds are defined as compounds with hydrogen bonds and inorganic compounds are not. Therefore, carbonic acid (H2CO3), carbon dioxide is an inorganic compound, but formic acid (also known as formic acid) (HCOOH, the first fatty acid) is an organic compound.
- Q: The difference between methanol fuel oil and alcoholized oil
- Methanol is best burned
- Q: Commodity fine chemical industry is good or organic intermediates synthesis is better?
- Domestic in terms of the day I think the high-end enterprises are not good into Such as Procter & Gamble Unilever, demanding, treatment Ye Hao, two intermediates is probably a little bit toxic, but do protective measures should be okay
- Q: Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not
- As long as carbon and carbon double bonds and three hydrocarbons can be hydrocarbons
