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

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

Q: Is not organic matter must not hydrogen ah?: Not without hydrogen, there must be C, but the material containing C is incomplete organic matter. Like H2CO3 and carbonate

Q: Is the oxygen derivative of the hydrocarbon a non-methane total hydrocarbon?: Hydrocarbon derivatives of hydrocarbons do not belong to non-methane total hydrocarbons

Q: Why not ah?: Ethylene is not a derivative of hydrocarbons, ethylene Chemical formula: CH2 = CH2

Q: Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even: The number of hydrogen atoms in the hydrocarbon must be even.

Q: What is organic?: Organic products are from the organic agricultural production system, according to the international organic agricultural production requirements and the corresponding standard production and processing, and through third-party geographical and organic certification bodies certified all agricultural and sideline products, including food, vegetables, fruits, dairy products, animal products , Honey, aquatic products, spices, cosmetics, and even textiles, forest products, biological pesticides, organic fertilizers and so on. Is the organic cultivation of pesticides, fertilizers, contaminated raw soils, grows in the closest way to nature, and never uses synthetic compounds, fertilizers and transgenic technologies during the growth process. In the process of production In the absence of any synthetic chemical composition. From the processing, production, packaging the whole process is in line with environmental protection and health principles. International standards of organic certification required by the third-year certification bodies from the cultivation, processing, production, manufacturing, to the finished product wholesale process for review.

Q: Why can organic matter be unique in chemical substances? What is the nature of the C atom?: Carbon, and can be spun, sp2, sp3 hybrid, so CH, CC, CO, CN, C = C, C = O, C = N and other covalent bonds can be formed and the key size is moderate, So these keys can also be more easily broken and generate new compounds. For silicon, the type of hybrid is mainly sp3 (no O = Si = O this molecule exists), but the Si-O bond bond energy is greater than Si-C, Si-Si, Si-H, so these keys are It is easy to break to produce SiO2, so there is the most natural Si-O compounds, and this compound is very stable, difficult to break down or other reactions.
