- Q:Identification of Derivatives of Chemical Hydrocarbons in High School
- Give you a formula: halogen water consumption, alcohol sodium oxygen consumption, phenolic acid picking, aldehyde plus oxidation.
- 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 cells are composed of compounds
- The organic matter that constitutes the cell generally refers to the general term for carbon-containing compounds or hydrocarbons and their derivatives. In nature, the types of organic matter are extremely numerous. Among them, organic compounds - carbohydrates, proteins and nucleic acids, which are composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, are the most important organic compounds in cells.
- Q:Why does toluene not belong to the derivatives of hydrocarbons?
- Hydrocarbon: sound tīng, is composed of two elements of carbon and hydrogen organic compounds known as hydrocarbons, also known as hydrocarbons. It reacts with chlorine, bromine, oxygen and other hydrocarbons to produce derivatives of hydrocarbons. Such as methane and chlorine in the light conditions of reaction to produce methyl chloride, dichloromethane, chloroform and chloroform (carbon tetrachloride) and other derivatives. The concept of derivatives is hydrocarbon and chlorine, bromine, oxygen and other reaction products. While toluene is not methyl and benzene, she is a whole noun is aromatic. Also known as aromatic hydrocarbons. Generally have one or more six-ring (benzene ring) with a special structure. The simplest aromatic hydrocarbons are benzene, toluene, xylene. There is also naphthenes. As the name suggests it is a ring structure. The most common is the five carbon atoms or six carbon atoms of the ring, the former called cyclopentane, which is called cyclohexane. The molecular formula of the cycloalkane is of the formula CnH2n. Cycloalkane is also called cycloalkane hydrocarbons. And alkanes. Is a carbon atom between the single bond phase chain hydrocarbon. Since the number of atoms that make up the hydrocarbon and hydrogen is different, the result is that the petroleum contains hydrocarbon molecules with large and small differences. Alkanes are named according to the carbon atoms and numbers contained in the molecule, and the number of carbon atoms is less than 10, from 1 to 10, followed by a, B, C, D, E, G, Alkane to say that the number of carbon atoms in more than 11, with the number that thank you to adopt
- 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:Are all carbon compounds all organic?
- Not ah, like CO, CO2, carbonated, carbonate is not ah
- Q:Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong
- Correct
- Q:What is the aromatic hydrocarbon .. what is the derivative of the aromatic hydrocarbon
- Aromatic hydrocarbons referred to as "aromatic hydrocarbons", refers to the molecule containing benzene ring structure of the hydrocarbons. Is a closed chain.
- Q:Is acrylamide an oxygen-containing derivative of hydrocarbons?
- From the structural point of view, alcohol, vinegar, malic acid, citric acid and other organic matter, can be seen as hydrocarbon molecules in the hydrogen atoms are replaced by oxygen atoms and atomic groups, they are known as hydrocarbon oxygen derivatives.
- Q:Is not organic matter must not hydrogen ah?
- Not without hydrogen, there must be C, but the material containing C is incomplete organic matter. Like H2CO3 and carbonate
