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: High school chemical hydrocarbons with hydrocarbon derivatives with water solubility, density for accurate and comprehensive summary, thank you. Out of college entrance examination
Hydrocarbons are insoluble in water and have a lower density than water
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: Is polyethylene a derivative of hydrocarbons?
No, the derivative of the hydrocarbon is an element other than c.H
Q: Are all carbon compounds all organic?
Not organic matter that is organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonates, metal carbides and other rare carbon compounds excluded) or hydrocarbons and their derivatives in general. Organic matter is the material basis for life.
Q: Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong
Organic compounds refer to hydrocarbons and their derivatives. Organic chemistry is the study of the structural characteristics of organic compounds, synthetic methods and physical and chemical properties of the chemical.
Q: From the molecular level, are not all the energy obtained from the redox reaction?
You find the block out of the lithium battery thrown into the fire try ........ look at how the energy density
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?
Organic carbon can be used in various architectures (ring, chain, short or long chain, twisted or planar aromatic or heterocyclic or naphthenes containing N / S / X halogen / P, etc.) Reaction mechanism (electrophilic addition, nucleophilic substitution, carbon positive ion intermediates, etc.). Due to the large negative carbon power is not great, the number of hybrid tracks can be 2 to 4 and not too much. For silicon, because of the electronegativity is less than hydrogen, resulting in silane hydrogen bonds in the biased hydrogen to make it easy to break, so silane in the air can be spontaneous combustion (not to mention disilane and above) The formation of compounds (similar to the alkyl) between the basic and hydrogen is so unstable that other similar compounds are difficult to stabilize.
Q: Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.
4. A wide variety of organic matter, hydrocarbons and hydrocarbons can be divided into two major categories of 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.
