- Q:Organic organic compounds are organic matter?
- The polymer compound is covalently bonded to each other by thousands of atoms to form a compound having a relatively large molecular mass and having a repeating structural unit. But the number of repeating units in the preparation process is often not the same, so that the organic polymer compound is a mixture of the argument is not wrong, of course it is organic matter which is beyond doubt.
- Q:Identification of Derivatives of Chemical Hydrocarbons in High School
- Phenol and ferric chloride reaction, aldehyde and copper hydroxide will produce brick red precipitation, and the formation of silver diamine hydroxide silver phase precipitation, and there are aldehydes in formic acid, an aldehyde corresponding to two silver Generation, and formaldehyde can be seen as there are two aldehyde groups, can be generated corresponding to the four silver quality.
- 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 are the oxygen consumption of the oxygen-containing derivatives of the mass hydrocarbons?
- For this comparison, you can see the experimental formula of this material, a C corresponds to an oxygen, 4 H corresponds to an oxygen, the experimental consumption of oxygen up, then under the same quality conditions, the greater the oxygen consumption of this material
- 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:Simply talk about hydrocarbons
- Hydrocarbon is a hydrocarbon compound. The organic compound consisting only of carbon and hydrogen is called a hydrocarbon and a hydrocarbon, which reacts with chlorine, bromine vapor, oxygen, etc. to produce a hydrocarbon derivative, Hydrocarbons (and benzene) do not react with strong acids, strong bases, strong oxidants (eg potassium permanganate), but unsaturated hydrocarbons (olefins, alkynes, benzene homologues) can be oxidized or react with hydrogen halide The
- Q:Chemical life network: chemical (inorganic reaction, organic reaction) is equal to the life of life reaction?
- Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic substances. It is the oldest branch of chemistry. All inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds (except for carbon dioxide, Carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.
- Q:Why the silicon hydride less, a lot of hydrocarbons. (Why did not you find silicon-based creatures) and why are so many oxides of silicon, little carbon oxides?
- You know silane bar, SiH4, this thing will be spontaneous, very unstable
- Q:Is polyethylene a derivative of hydrocarbons?
- No, the derivative of the hydrocarbon is an element other than c.H
- Q:What is the hydrocarbon thing
- Hydrocarbon, which is composed of two elements, consists of carbon and hydrogen. It is called a hydrocarbon and a hydrocarbon, which reacts with chlorine, bromine vapor, oxygen and so on. It does not react with strong acid, strong base, strong oxidizer (Such as: potassium permanganate) reaction, such as methane and chlorine in the light conditions of reaction to produce methyl chloride, dichloromethane, chloroform (chloroform) and tetrachloromethane (carbon tetrachloride) and other derivatives in the Hydrocarbon molecules in the carbon atoms connected to each other to form a carbon chain or carbon ring molecular skeleton, a certain number of hydrogen atoms attached to the carbon atoms, so that each carbon atom to maintain the price of the type of hydrocarbon is very much, the structure of known hydrocarbons More than 2,000 hydrocarbons are the parent of an organic compound. Other organic compounds can be seen as derivatives of one or more hydrogen atoms in the hydrocarbon molecule that are replaced by atoms or radicals of other elements. Word, is the use of "carbon" consonant with "hydrogen" vowel synthesis of a word, with "carbon" and "hydrogen" the composition of the internal structure of the word, the hydrocarbon is the parent of all organic compounds can be said that all Organic compounds are nothing but the result of replacing some of the atoms in the hydrocarbons with other atoms.
