Q:What are the derivatives of hydrocarbons?

Halogenated hydrocarbons, alcohols

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:The role of aromatic hydrocarbons

Two cases: First, the name of monocyclic aromatic hydrocarbons, usually benzene ring for the mother, alkyl as a substituent. Second, the structure is more complex aromatic hydrocarbons, usually based on the hydrocarbon base, benzene ring as a substituent. Xylene, 2-methyl-3-phenylpentane, diphenylmethane, etc. For the naming of multifunctional compounds, attention is given to the priority order of the functional groups. The priority is preceded by the parent, usually: cations, COOH SO2H, COOR, COCl, CONH2, CN, CHO, CO, OH, SH, NH2, alkynes, alkenes, ethers, X, NO2, etc. [2]

Q:What is the hydrocarbon thing

Hydrocarbons can be divided into: open chain hydrocarbons (carbon atoms in hydrocarbon molecules in open chain) - saturated hydrocarbons - alkanes - unsaturated hydrocarbons - olefins and polyolefins (carbon - carbon double bonds, unstable) - alkynes and (Cyclopentane) - cycloalkene - cycloalkyne aromatic hydrocarbon - monocyclic aromatic hydrocarbon (benzene and its homologues) - fused ring aromatic hydrocarbons (Polycyclic aromatic hydrocarbons and their homologues) - polycyclic aromatic hydrocarbons (naphthalene, anthracene and other condensed ring aromatic hydrocarbons and their homologues) all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water and coal The main ingredients are hydrocarbons

Q:Compare the difference between London smoke and Los Angeles photochemical smog

Los Angeles photochemical smog nitrogen content and hydrocarbons and derivatives more, mainly close to the car exhaust. Foggy London situation related to coal, soot solid particles and sulfur oxide more. Foggy London is more bleak, and Los Angeles is more toxic.

Q:Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?

The heterocyclic compound is an organic compound containing a heterocyclic structure in its molecule. The atoms that make up the ring contain at least one heteroatom in addition to carbon atoms. The heteroatoms include oxygen, sulfur, nitrogen and the like. Theoretically, the heterocyclic compound can be regarded as a derivative of benzene, that is, one or more CH in the benzene ring is replaced by a heteroatom. The heterocyclic compound may be in parallel with the benzene ring to form a fused ring heterocyclic compound.

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?

Inorganic matter is an inorganic compound. Generally refers to the elements other than carbon elements, such as water, salt, sulfuric acid, lime and so on. However, some simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides, because of their composition and properties and inorganic similar, so also as an inorganic to study. The vast majority of inorganic matter can be classified as oxides, acids, alkalis and salts.

Q:What cells are composed of compounds

Protein and water

Q:Are hydrocarbons all organic?

A series of organic compounds, also known as "hydrocarbons." Many types, according to the structure and nature,
