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: 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: Why is dry ice not organic?: Organic compounds are mainly composed of oxygen, hydrogen, and carbon, and organic matter is the material basis for life.

Q: Will AsH3 (arsenic trioxide) is organic or inorganic: AsH3 (arsine trihydride) is not containing C element

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: 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 is the difference between hot and cold asphalt?: I only heard the warm mix of asphalt. The How is cold asphalt defined? How much is it cool?

Q: What cells are composed of compounds: Water, various inorganic salts, sugars (mainly glucose and sugar), nucleotides, amino acids, lipids

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: Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons: A little bit of a way to draw out with chemdraw, then convert structure to name
