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:What is the difference between crude oil and asphalt?

Difference: 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. Crude oil (44.27,0.27,0.61%) is the upstream raw material of asphalt, there is a strong correlation between the two prices. For the asphalt industry, the impact of the upstream industry is mainly reflected in the fluctuations in crude oil prices, crude oil processing capacity changes in oil asphalt production and product prices fluctuations. From the downstream demand point of view, asphalt products are mainly used in highways, municipal roads, bridges and airports and other places of the laying of which highway construction for the consumption of asphalt accounted for 82%. In the case of a certain capacity, the increase in downstream demand will further promote the growth of asphalt prices, on the contrary, will bring the price down.

Q:Is steel not organic synthetic material?

Steel is a mixture, the vast majority of elemental iron, also contains other elements, carbon is mixed in the inside, and did not constitute a compound.

Q:What is the difference between organic matter and inorganic matter?

Organic compounds in addition to a few, can generally burn. Compared with inorganic matter, their thermal stability is relatively poor, the electrolyte is easy to heat decomposition. The melting point of organic matter is low, generally not more than 400 ℃. The polarity of organic matter is very weak, so most of the water is not soluble. The reaction between organic matter, mostly intermolecular reactions, often requires a certain activation energy, so the reaction is slow, often requiring catalyst and other means. And the reaction of organic matter is more complex, under the same conditions, a compound can often be several different reactions at the same time, generate different products.

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:Artemisinin is not a derivative of hydrocarbons

A hydrocarbon is an organic compound (called a hydrocarbon) composed of two elements, carbon and hydrogen, and a hydrocarbon. Can be simply divided into open chain hydrocarbons, alicyclic hydrocarbons and aromatic hydrocarbons, all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water.

Q:What is the meaning of organic ah, organic food on the human body what practical benefits

Food point of view of organic: from planting to harvest, and then to storage, transport so that consumers in the hands, without chemical fertilizers, chemical processing, genetic technology and other food raw materials. In general, organic represents high quality and natural. But the Chinese market is not very close, so the choice of time to pay attention.

Q:Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.

Organic matter is an abbreviation for organic compounds. At present, human beings know more than 900 million kinds of organic matter, the number is far more than inorganic.

Q:What is the difference between an aromatic compound and a hydrocarbon derivative?

The aromatic compound is a benzene ring containing compound, which may be a hydrocarbon or a hydrocarbon derivative. Hydrocarbons are hydrocarbon-containing compounds, and hydrocarbons containing hydrocarbons other than hydrocarbons are derivatives of hydrocarbons. The two concepts have crossed.

Q:Why is dry ice not organic?

Organic compounds are mainly composed of oxygen, hydrogen, and carbon, and organic matter is the material basis for life.
