Q: What is organic matter?: Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.

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: 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: 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: Artemisinin is not a derivative of hydrocarbons: A hydrocarbon is an organic compound (called a hydrocarbon) composed of two elements, carbon and hydrogen, and a hydrocarbon. Can be simply divided into open chain hydrocarbons, alicyclic hydrocarbons and aromatic hydrocarbons, all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water.

Q: What is "organic" and "inorganic" in chemistry?: Carbon compounds, not carbon oxides, carbonates, bicarbonates are organic matter

Q: Sodium can be used to identify derivatives of hydrocarbons: The alcohol reacts with sodium. (Such as phenolic C6H5OH, cresol CH3C6H4OH, etc.), carboxylic acids (such as formic acid HCOOH, acetic acid CH3COOH, etc.) (description: hydroxyl groups in the carboxylic acid are hydroxyl groups in the carboxyl group) and hydroxyl groups containing polyhydroxyaldehydes and polyhydroxy ketones Such as glucose, fructose, etc.)

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: Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons: Pro-butylbenzene ethane

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.
