Q: What is carbohydrate? What is organic? What is it?: Most organic compounds mainly contain carbon, hydrogen two elements, in addition often contain oxygen, nitrogen, sulfur, halogen, phosphorus and so on. Part of the organic matter from the plant sector, but the vast majority of oil, natural gas, coal as raw materials, through artificial synthesis method. Compared with inorganic substances, the number of organic matter, up to several million kinds. The carbon atoms of the organic compound have a very strong ability to bind to each other to form a carbon or carbocyclic ring. The number of carbon atoms can be 1,2, it can be thousands, tens of thousands, many organic polymer compounds can even have hundreds of thousands of carbon atoms. In addition, the isotopic phenomenon of organic compounds is very common, which is one of the reasons for the many organic compounds. Organic compounds in addition to a few, can generally burn. Compared with inorganic matter, their thermal stability is relatively poor, the electrolyte is easy to heat decomposition. The melting point of organic matter is low, generally not more than 400 ℃. The polarity of organic matter is very weak, so most of the water is not soluble. The reaction between organic matter, mostly intermolecular reactions, often requires a certain activation energy, so the reaction is slow, often requiring catalyst and other means. And the reaction of organic matter is more complex, under the same conditions, a compound can often be several different reactions at the same time, generate different products.

Q: Ionic compounds, covalent compounds, electrolytes, non-electrolytes, which are both compounds and inorganic compounds: They are different concepts -

Q: Organic organic compounds are organic matter?: Organic polymer compounds are organic matter

Q: Is polyethylene a derivative of hydrocarbons?: The definition is yes

Q: Identification of Derivatives of Chemical Hydrocarbons in High School: Meaning that the halogenated hydrocarbon can be hydrolyzed and eliminated; the alcohol reacts with sodium to produce oxidation and eliminate the reaction; the phenol has acidity, can replace the reaction and color reaction; aldehyde can be added reaction and oxidation reaction. Finally remember the acid and acid, and alcohol esterification reaction.

Q: Hydrocarbons and hydrocarbon derivatives are not all non-electrolytes: Hydrocarbons are, derivatives are not necessarily, such as organic acids (formic acid, acetic acid, etc.)

Q: Does Organic Chemistry Study the Performance of Hydrocarbons and Their Derivatives?: Also study the structure and transformation

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: Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons: A little bit of a way to draw out with chemdraw, then convert structure to name

Q: How the most primitive life on earth is produced under what conditions: The most primitive creatures on earth are actually RNA, which is pulled earlier than any prokaryotic cells, and the eukaryotic cells are advanced, in short, the chemical reaction in the environment at that time.
