- 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: Why does the molecular atom compound do not belong to the life structure
- Life structure is composed of CHO as the main element through the covalent bond of the combination of hydrocarbons and their derivatives, and you said the molecular atomic compounds are usually atomic or ionic bond
- 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: 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
- Pentane, g, x, n, decane, to eleven to hexadecane are liquid hydrocarbons. Ethanol is not a hydrocarbon, it is aerobic. Polymeric material is a compound of relatively high molecular weight Composition of the material, there are many, such as rubber, plastic, fiber, paint
- Q: Does Organic Chemistry Study the Performance of Hydrocarbons and Their Derivatives?
- Also study the structure and transformation
- 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 organic matter? Candle is organic?
- For example: CH4 C2H6O and so are organic matter
- Q: Organic intermediates in the synthesis, what is the chemical choice
- Choose the first reaction that is easy to react quickly
- Q: Carboxylic acid in the end can not react with the new copper hydroxide
- But the formula is written in the carboxylic acid, because the reaction of aldehydes with the new copper hydroxide is alkaline conditions, the carboxylic acid is not present, but the carboxylic acid and alkali, copper hydroxide, copper oxide are reaction, Side reactions too much, too complex, in order to show that the reaction principle, simply from the simple processing, directly write carboxylic acid
- Q: The nature and use of cellulose derivatives
- The basic rules of esterification and etherification of cellulose In the cellulose molecule, the position of the three hydroxyl groups in the glucose group is different, and the influence of the adjacent substituents and the spatial blocking effect are different. The relative acidity and dissociation of the three hydroxyl groups are: C> C> C When the etherification reaction is carried out in the alkaline medium, the C hydroxyl group first reacts, then the C hydroxyl group, and finally the C primary hydroxyl group. In the acidic medium for esterification reaction, the reaction of the hydroxyl reaction is difficult and etherification reaction in the opposite order. When reacted with a larger amount of substituted reagents, the spatial hindrance has an important effect, and the space hindering the smaller C hydroxyl groups is easier to react than C and C hydroxyl groups.
