- Q:What is the definition of organic matter
- Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
- Q:What does organic and inorganic mean?
- Organic and inorganic machine myself ~ female and male
- Q:Why is dry ice not organic?
- Inorganic compounds are pure metals that do not contain carbon and a collection of simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides.
- Q:Inorganic chemistry employment direction? Current research direction
- Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic matter, which is the oldest branch of chemistry. Inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds. (In addition to carbon dioxide, carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.) Inorganic chemistry is in addition to hydrocarbons and their derivatives, the nature of all elements and their compounds And their reaction to experimental research and theoretical interpretation of science, is the development of the discipline of the earliest branch of a discipline.
- 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: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:The functional group of the derivative of the hydrocarbon
- Yes, the number of carbon after a certain, only to determine the nature of the functional group. This is also the reason for the name of the functional group
- 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:Are the asphalt and peat kinds of vegetables have heavy metal?
- Asphalt is a hydrophobic material, it is impermeable, and almost insoluble in water, acetone, ether, dilute ethanol, dissolved in carbon disulfide, carbon tetrachloride, sodium hydroxide.
- Q:Cracked
- It is almost impossible for this problem to look at your reaction conditions. Generally speaking, the alkane reaction is mainly difficult to decompose directly into ions
