- 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: Is carbon monoxide an organic gas?
- Carbon dioxide is highly toxic. It is a strong ability to combine blood hemoglobin, which leads to cell hypoxia and suffocation. At present, if the trace carbon monoxide environment work, do not wear a gas mask and other necessary, it is recommended to eat more iron and calcium foods to reduce the harm to the body.
- 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: What is a derivative of a hydrocarbon? What is an aromatic hydrocarbon derivative?
- Hydrocarbon derivatives include derivatives of linear and aromatic hydrocarbons such as chloroethane bromopropane bromobenzene
- Q: What is the relationship between hydrocarbon and hydrocarbon derivatives?
- The hydrocarbon is the parent of the organic compound, and the other various organic compounds can be regarded as derivatives of one or more hydrogen atoms in the hydrocarbon molecule being replaced by atoms or radicals of other elements.
- 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: Does Organic Chemistry Study the Performance of Hydrocarbons and Their Derivatives?
- Also study the structure and transformation
- Q: Is the system name of a hydrocarbon derivative named if the question can be named according to the nomenclature of the alkane?
- Halogen can be named after the alkane, the other can not
- Q: Such as the title, the personal feeling of chemical transliteration of Chinese transliteration can be done so easy to write, weird name in addition to keep the high point, no good, but rather affect the people's understanding of medicine and memory, contrary to the text to facilitate the exchange of memory Original intention
- China's chemical name may be the best of both Latin and English
- Q: Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.
- 3. Organic matter is generally insoluble in water, soluble in organic solvents, low melting point. 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.
