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: Does the carboxylic acid react with the Grignard reagent?: Reaction. Grignard reagent is an organic strong base, first and the acid reaction of carboxylic acid to produce magnesium salt, and sometimes further nucleophilic attack, control conditions will get different products, but the first acid-base reaction is unavoidable.

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

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: (3) polyethylene (2) is not, is a hydrocarbon derivative, there are C, H, O elements (3) polyethylene material (polyethylene material non-stick pan) (4) oil and oil produced gasoline is liquid , The general organic polymer materials can be burned

Q: Carboxylic acid and alcohol can react, is it necessary to have certain conditions, if the conditions can not reach, is not it can not respond?: This is not you know the wine wine fruit flavor from ethyl acetate it is ethanol and acetic acid esterification out of the esterification of the esterification reaction needs to concentrate sulfuric acid catalysis that is because the laboratory to yield to the speed So it is necessary to reduce the activation energy to try their esterification but miscible case will react but very very slow wine more Chen Yue Hong to wait ten years or even hundreds of you will not be willing to do so

Q: What is the meaning of organic ah, organic food on the human body what practical benefits: Chemical point of view, organic is organic matter, mainly by the carbon atoms and hydrocarbons derivatives.

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: What are the characteristics of organic compounds?: Organic compounds are usually referred to as carbon-containing compounds, or hydrocarbon-containing compounds and their derivatives are collectively referred to as organic matter. Organic compounds are generally insoluble in water and soluble in organic solvents with lower melting points. The vast majority of organic matter heat easily decomposed, easy to burn. The reaction of organic matter is generally slow and often accompanied by side effects, and there are many kinds of organic compounds, which can be divided into two major categories of hydrocarbon and hydrocarbon derivatives. According to the organic groups contained in the functional groups, divided into alkanes, alkenes, alkynes, aromatic hydrocarbons and alcohols, aldehydes, carboxylic acids, esters and so on. According to the organic carbon molecular structure, can also be divided into open chain compounds, carbocyclic compounds and heterocyclic compounds three categories.

Q: Other corals are because the color of the corals show colorful, why only the red coral is the exception of it? did not find the reasons for the big god to explain: Red coral is not absorbed red, so it looks red.

Q: Is the carboxylic acid derivative and the substituted carboxylic acid the same concept?: Carboxylic acid derivatives mainly include: 1. Esters 2. Acyl halides such as acetyl chloride: CH3-COCl3. Acids such as acetic anhydride: (CH3CO) 2O4. Amides such as acetamide: CH3CONH2
