Q: What is the isomeric structure of oxygen-containing derivatives?: Play the Transformers. As long as the same molecular formula, you can group out how many different structures, there are a number of isomers.

Q: Ionic compounds, covalent compounds, electrolytes, non-electrolytes, which are both compounds and inorganic compounds: The covalent compound is a compound molecule composed of a common electron pair between atoms. When two nonmetallic elements (or inactive metal and nonmetallic elements) are combined, one or more electrons are formed between the atoms, and the electron pair is attracted by two nuclei, and the two atoms are common , So that two atoms form compound molecules. For example, hydrogen chloride is a hydrogen atom and chlorine atoms each with the outermost layer of electrons to form a common pair of compounds composed of compounds. Non-metallic hydrides (such as HCl, H2O, NH3, etc.), non-metallic oxides (such as CO2, SO3, etc.), anhydrous acids (such as H2SO4, HNO3, etc.), most organic compounds (such as methane, Are covalent compounds. Most covalent compounds in the soli

Q: What is the difference between an aromatic compound and a hydrocarbon derivative?: The aromatic compound is a benzene ring containing compound, which may be a hydrocarbon or a hydrocarbon derivative. Hydrocarbons are hydrocarbon-containing compounds, and hydrocarbons containing hydrocarbons other than hydrocarbons are derivatives of hydrocarbons. The two concepts have crossed.

Q: Identification of Derivatives of Chemical Hydrocarbons in High School: Phenol and ferric chloride reaction, aldehyde and copper hydroxide will produce brick red precipitation, and the formation of silver diamine hydroxide silver phase precipitation, and there are aldehydes in formic acid, an aldehyde corresponding to two silver Generation, and formaldehyde can be seen as there are two aldehyde groups, can be generated corresponding to the four silver quality.

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: What are the derivatives of hydrocarbons?: In addition to the C and H elements, there are also one or more of O, X (halogen), N, S and other elements, such as methanol (CH3OH) learned from junior high school chemistry, (CH3Cl), nitrobenzene (C6H5NO2), and the like, which are mentioned in the previous chapter, are derivatives of hydrocarbons, such as ethanol (C2H5OH), acetic acid (CH3COOH)

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

Q: Is grease a polymer compound? Is it a derivative of saturated hydrocarbons?: Grease is not a polymer, a hydrocarbon (not necessarily a saturated hydrocarbon) derivative,

Q: Why can organic matter be unique in chemical substances? What is the nature of the C atom?: Organic this historical term, can be choked to the 19th century, when the students that organic compounds can only be biological (life-force, vis vitalis) synthesis. This theory is based on organic matter and "inorganic" the basic difference, organic matter can not be non-vitality synthesis. But later this theory was overthrown, the German chemist Friedrich W?hler to cyanide and ammonia synthesis of urea (inorganic synthesis of organic matter). In general, organic compounds are defined as compounds with hydrogen bonds and inorganic compounds are not. Therefore, carbonic acid (H2CO3), carbon dioxide is an inorganic compound, but formic acid (also known as formic acid) (HCOOH, the first fatty acid) is an organic compound.
