Q: What is carbohydrate? What is organic? What is it?
Compounds associated with the body (a few of the body-related compounds are inorganic compounds, such as water), usually carbon-containing compounds, but some simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, metal carbides, cyanides And so on. In addition to carbon containing elements, the vast majority of organic compounds containing hydrogen molecules in the molecule, and some also oxygen, nitrogen, halogen, sulfur and phosphorus and other elements. There are nearly 6 million organic compounds known. In the early days, organic compounds were substances that were obtained from animals and plants. Since 1828, the boundary between organic matter and inorganic matter disappears after artificial synthesis of urea [(NH2) 2CO], the term "organic" is still used for historical and customary reasons. Organic compounds are of great importance to humans, and all forms of life on earth, mainly composed of organic matter. For example: fat, amino acids, protein, sugar, heme, chlorophyll, enzymes, hormones and so on. Biological metabolism and biological genetic phenomena, are related to the transformation of organic compounds. In addition, many substances closely related to human life, such as oil, natural gas, cotton, dyes, chemical fiber, natural and synthetic drugs, are organic compounds.
Q: What is the relationship between hydrocarbon and hydrocarbon derivatives?
Hydrocarbons, which are composed of two elements, carbon and hydrogen, are called hydrocarbons and hydrocarbons. It reacts with chlorine, bromine vapor, oxygen, etc. to produce hydrocarbons.
Q: Are all carbon compounds all organic?
Not organic matter that is organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonates, metal carbides and other rare carbon compounds excluded) or hydrocarbons and their derivatives in general. Organic matter is the material basis for life.
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
1. A hydrocarbon containing five to eight carbons 2. Not, it is an oxygen-containing derivative of a hydrocarbon 3. A hydrocarbon and a halogenated hydrocarbon (unsaturated) polymer, an alcohol, a phenol and
Q: What is the difference between organic matter and inorganic matter?
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: 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
Q: What is the most primitive person on earth?
In the 4 billion years ago, the Earth's water environment, the atomic group into molecules, the formation of a new four-balance body, and the Earth in the formation process, has gathered a lot of interstellar organic molecules, these molecules combined into macromolecules, Of the gravitational field and the anti-gravitational field to find the appropriate combination of objects. Macromolecules, molecules and atoms are also dependent on the formation of the force field to find the appropriate combination of objects, the formation of a new complex four-force balance body, where the gravitational field to play a long-range attraction (5-20 atomic diameter), which It also limits the macromolecules to obtain the desired combination of objects on a large scale, so macromolecules are combined into a moving tissue form, the most primitive marine microorganism. The macromolecules that move can mainly use the method of orienting the electromagnetic force to gradually develop into the original tissue that can swim in the water, so they can obtain a large amount of food (four-force balance) and accumulate some molecules in the body , These molecules in the original microbial parent force field guidance, combined with the mother similar to the new micro-organisms, these primitive microorganisms is essentially a complex macromolecule formation of the four balance body, which is the prototype of biological gene replication.
Q: The aromatic hydrocarbon derivative refers to monocyclic or polycyclic
To see what is the derivative of aromatic hydrocarbons, by its own is a single ring or multi-ring decision
Q: From the molecular level, are not all the energy obtained from the redox reaction?
Because one to be recycled, and secondly to be converted into electricity
Q: Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?
Hydroxyls are directly attached to charcoal and alcohols are derivatives of hydrocarbons.
