Q:Organic organic compounds are organic matter?

The polymer compound is covalently bonded to each other by thousands of atoms to form a compound having a relatively large molecular mass and having a repeating structural unit. But the number of repeating units in the preparation process is often not the same, so that the organic polymer compound is a mixture of the argument is not wrong, of course it is organic matter which is beyond doubt.

Q:How to distinguish between inorganic chemicals and organic chemicals

If the chemical can be dissolved in water, then it is likely that inorganic chemicals, because organic chemicals only a few substances such as ethanol and acetic acid can be dissolved in water. In addition, inorganic chemicals are mostly solid or aqueous solution, and organic chemicals are mostly liquid and odor.

Q:Is the resin a dangerous chemical? Is there any other alias?

Do not know what kind of resin you said.

Q:What is a derivative?

Derivative refers to a complex compound in the hydrogen atoms or atomic groups replaced by other atoms or atomic groups derived more complex products.

Q:Compare the difference between London smoke and Los Angeles photochemical smog

Los Angeles photochemical smog nitrogen content and hydrocarbons and derivatives more, mainly close to the car exhaust. Foggy London situation related to coal, soot solid particles and sulfur oxide more. Foggy London is more bleak, and Los Angeles is more toxic.

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:What are the most stable carboxylic acid derivatives?

In addition to acid halide are more stable, which ester and amide stability is stronger

Q:What are the sugars?

Carbohydrate carbohydrates, also known as carbohydrates, are the most widely distributed and most important organic compounds in the world. Glucose, sucrose, starch and cellulose are all carbohydrates. X0d carbohydrates are all organisms The main source of energy needed to sustain life activities is not only nutritious but also has special physiological activity, such as: heparin in the liver has anticoagulant effect; blood sugar in the blood type related to immune activity.In addition, the nucleic acid The carbohydrate compounds are more important for medicine, and the carbohydrate compounds are composed of three elements, C, H and O, And O is usually 2: 1, and the proportion of water molecules, which can be expressed by the general formula Cm (H2o) n.Therefore, these compounds have been called carbohydrates, but later found that some compounds according to their structure and (C6H12O5), deoxyribose (C5H10O4), etc .; and some compounds such as acetic acid (C2H4O2), lactic acid (C3H6O3), and other compounds, such as acetic acid (C2H4O2), lactic acid (C3H6O3) And its composition is consistent with the general formula Cm (H2o) n, but the structure and properties are completely different with the carbohydrate compounds, so the name of the carbohydrate is not exact, but for a long time, so far still in use. X0d from Chemical structures, carbohydrates are polyhydroxyaldehydes, polyhydroxy ketones, and their condensates. <X0d sugars can be divided into three categories according to the hydrolysis and hydrolysis products: x0d monosaccharides: polyhydroxyalides that can not be hydrolyzed Such as glucose, fructose, etc. x0d disaccharides: hydrolysis of sugar to produce two molecules of monosaccharides such as sucrose, maltose, etc. x0d polysaccharide: can be hydrolyzed to produce many molecules of sugar monosaccharides such as starch, glycogen, Cellulose, etc. x0d sugars often use their names according to their origin.

Q:What are the characteristics of the reduction of carboxylic acid and its derivatives?

NaBH4-ZrCl4 reagent system In the THF-toluene mixed solvent, at the reflux temperature, some of the carboxylic acid and its derivatives can be reduced to obtain the corresponding high yield of alcohol.

Q:Organic chemistry, carboxylic acid derivatives are not acid?

According to acid-base ionization theory and proton theory, not; according to acid-base theory, some is
