Stearic Acid 1680

Q:NH4HCO3 and so have C atoms ah, why still inorganic: Organic matter is a general term for carbon compounds (except carbon oxides, carbon dioxide, carbonates, carbonates, bicarbonates, metal carbides, cyanides, thiocyanides and other oxides) or hydrocarbons and their derivatives. Organic matter is the material basis for life. The inorganic compound usually refers to a compound containing no carbon element, but a few carbon-containing compounds such as carbon dioxide, carbonic acid, carbon monoxide, carbonate and the like do not have the properties of an organic substance, and therefore such substances are also inorganic.

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:Why does the molecular atom compound do not belong to the life structure: Life structure is composed of CHO as the main element through the covalent bond of the combination of hydrocarbons and their derivatives, and you said the molecular atomic compounds are usually atomic or ionic bond

Q:Rush! Hydrocarbon and hydrocarbon derivatives system information includes chemical formula, common name, Chinese name and so on: hydrocarbon

Q:The functional group of the derivative of the hydrocarbon: Common functional groups are: carbon-carbon double bond, -OH-COOH-CHO-NH2, often react, replace (including halogenation, nitration, sulfonation, esterification, hydrolysis, etc.), addition, elimination, addition polymerization , Organic matter oxidation and reduction, color and so on.

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.

Q:Can the carboxylic acid react with sodium?: can

Q:Simply talk about hydrocarbons: Hydrocarbon products in the daily production, life is widely used, the most representative of the commercial life of the HCR433b hydrocarbon refrigerant, and the most representative of the automotive HCR436a hydrocarbon refrigerant.

Q:Is the resin a dangerous chemical? Is there any other alias?: Do not know what kind of resin you said.

Q:What is the derivative of benzene?: Benzene homologues: the structure of similar molecular composition of a number of different groups of CH2 atoms.
