What are organic and inorganic? junior high school .

To put it simply, organic matter is a compound that contains carbon, and inorganic matter is a compound that does not contain carbon. However, the following carbon-containing compounds are inorganic because their properties are close to those of other inorganic substances:

CO, CO2, H2CO3, carbonate (RCO3), (CN)2 (cyanide), HCN (hydrocyanic acid), HCNO (cyanic acid), hydrocyanate (RCN), cyanate (RCNO), carbon disulfide, calcium carbide and other metal carbides, etc. In junior high school chemistry, (CN)2, HCN, HCNO, hydrocyanate, cyanate, carbon disulfide, calcium carbide and other metal carbides are not required, but you can learn about them.

Determining whether a substance is organic or not can generally be judged by the method of combustion. However, although most inorganic substances cannot be burned, there are some inorganic substances that can be burned (such as CO, etc.) and some organic substances that cannot be burned.

The biggest difference between organic matter and carbon-containing inorganic matter is that C in organic matter is used as the skeleton in organic matter, connected to other elements such as H, O, and N. Whereas, C in carbon-containing inorganic compounds does not act as the backbone of the compound.

The main composition of organic compounds is C, and general organic matter often contains three elements, such as C, H, and O, and many organic substances also contain elements such as N and P. The simplest organic matter is methane, with the chemical formula CH4, relative molecular weight 16, gas at room temperature, flammable, and combustion products of water and carbon dioxide.

In history, there was the "life force theory", which was put forward by Berzirius, which specifically means that people cannot synthesize organic matter by themselves, and organic matter can only be produced by a kind of "life force" in living organisms. Later, with the synthesis of urea (CO(HN2)2 from cyanic acid (HCNO) and ammonia (HN4OH), and later the ability to synthesize organic compounds from elemental matter, the "vitality theory" declared bankrupt.

Organic matter is a compound containing carbon, and inorganic matter is a compound that does not contain carbon (except for individual carbon-containing compounds, such as CO, CO2, H2CO3).

Hehe, I'm a freshman in high school, and I just learned this thing, and the teacher said that what contains C is organic matter, except for carbonate, co, and carbon dioxide.

Organics refer to carbon-containing elements.

compounds. Carbon oxides, carbonate salts and metal carbides are removed. (For example, carbon dioxide.)

Sodium carbonate, etc., is not organic).

Inorganic: Generally refers to substances that do not contain carbon in their composition. Including elemental, carbon oxides, carbonate (hydrogen) salts and metal carbides.

The molecules of organic matter generally form a very long carbon-carbon chain, which is often a large molecular weight substance and has some special properties, so it is specially divided into a large category.

Common organic substances in daily life are plastics, rubber, and so on.

Commonly used organic raw materials in industry: ethylene, acetylene, propylene, butylene, isoprene, methanol.

Ethanol, ether, formaldehyde, acetaldehyde, acetone.

Formic acid, acetic acid, etc.

I'll try to be as plain as possible, but if you want to know more about it, you still have to learn the basics of chemistry.

Organics are organic compounds. A general term for carbonaceous compounds (except for a few simple carbonaceous compounds such as carbon monoxide, carbon dioxide, carbonates, metal carbides) or hydrocarbons and their derivatives. Organic matter is the material basis for the production of life.

Characteristics of organic matter:

Most organic compounds mainly contain carbon and hydrogen, and often contain oxygen, nitrogen, sulfur, halogens, phosphorus, etc. Some organic matter comes from the plant kingdom, but most of them are made from oil, natural gas, coal, etc. as raw materials, and are prepared by artificial synthesis.

Compared with inorganic matter, the number of organic matter is numerous, up to several million. The carbon atoms of organic compounds are very strong in binding capacity and can combine with each other to form carbon chains or carbon rings. The number of carbon atoms can be one, thousands, tens of thousands, and many organic polymer compounds can even have hundreds of thousands of carbon atoms.

In addition, isomerism is very common in organic compounds, which is one of the reasons for the abundance of organic compounds.

Organic compounds are generally combustible except for a few. Compared with inorganic substances, they have poor thermal stability, and electrolytes are prone to decomposition when heated. The melting point of organic matter is low, generally not exceeding 400.

The polarity of organic matter is very weak, so it is mostly insoluble in water. The reaction between organic matter, most of which is an intermolecular reaction, often requires a certain amount of activation energy, so the reaction is slow, and catalysts and other means are often needed. Moreover, the reaction of organic matter is more complex, under the same conditions, a compound can often carry out several different reactions at the same time to produce different products.

Inorganic substances are inorganic compounds. Generally, it refers to the compounds of various elements other than carbon, such as water, salt, sulfuric acid, lime, etc. However, some simple carbon-containing compounds such as carbon monoxide, carbon dioxide, carbonic acid, carbonates, and carbides are also studied as inorganic due to their similar composition and properties to inorganic substances.

The vast majority of inorganic substances can be classified into four categories: oxides, acids, bases, and salts.

In layman's terms, organic matter and inorganic band spring matter are the two basic categories in chemistry.

In general, organic matter refers to a compound with carbon atoms as the backbone, while inorganic matter refers to everything else else, inorganic matter is an abbreviation for inorganic compound, which usually refers to a compound that does not contain the element carbon. They usually contain no carbon or only a very small amount of carbon. In the field of biology and geochemistry, these two categories of substances have many special definitions and regulations, but this basic definition is generally followed.

Since organic matter is mainly found in living organisms, while inorganic matter is more present in non-living organisms, both of which are very different in terms of chemical and physical properties, chemical reactions, etc. For example, organic matter tends to burn easily in the air, while inorganic matter is more stable and less flammable. In addition, since organics are composed of many compounds of different types, their characteristics and properties also differ, so the corresponding chemicals need to be selected according to the specific situation in practical applications.

In a narrow sense, organic compounds mainly refer to compounds composed of carbon and hydrogen elements, which must be carbon-containing compounds, but do not include carbon oxides and sulfides, carbonic acid, carbonates, cyanides, thiocyanides, carbides, carboranes, carbonyl** genus, metal-organic ligand complexes without M-C bonds, and some metal-organic compounds (substances containing M-C bonds) and other carbon-containing substances mainly studied in inorganic chemistry.

The original meaning of "organic matter" is a substance derived from living organisms, because the organic matter discovered in the early days was isolated from living organisms. With the development of organic synthesis, many organic substances can be synthesized by inorganic substances in the laboratory. The word "organic" has lost its original meaning.

Organic matter is the material basis for the production of life, and all living organisms contain organic compounds, such as fats, amino acids, proteins, sugars, heme, chlorophyll, enzymes, hormones, etc. The metabolism of organisms and the genetic phenomena of organisms are involved in the transformation of organic compounds. In addition, many substances that are closely related to human life, such as oil, natural gas, cotton, dyes, chemical fibers, plastics, plexiglass, natural and synthetic drugs, etc., are closely related to organic compounds.

1.Organics are a general term for carbon-containing compounds (except carbon-oxides, carbon sulfides, carbonic acid, carbonates, bicarbonates, metal carbides, cyanides, thiocyanides, carboranes, alkanes, carbonyls, organic ligand complexes of metals, etc.) or hydrocarbons and their common derivatives.

3.Many inorganic compounds are carbon-free compounds, but some carbon-containing compounds, such as carbon dioxide and carbon monoxide, do not have the properties of organic substances, so such substances are also inorganic.

4.In addition to the carbon-containing element tung tong, organic compounds may also contain elements such as hydrogen, oxygen, nitrogen, chlorine, phosphorus and sulfur.

5.Carbon also plays an almost irreplaceable role in inorganic chemistry, and metal carbonyl clusters occupy half of today's inorganic chemistry.

6.Therefore, organic compounds are all carbonaceous compounds, but carbonaceous compounds are not necessarily organic compounds.

7.Inorganic compounds, compounds that are not related to the body (a few compounds related to the body are also inorganic compounds, such as water), corresponding to organic compounds, usually refer to compounds that do not contain carbon elements, but include carbon-containing carbon oxides, carbonates, cyanides, carbides, carboanes, carbonyls, alkanes, organic ligand complexes of metals, etc., referred to as inorganics.

8.Inorganic matter refers to the collection of pure substances that do not contain carbon elements and some carbon-containing compounds, such as carbon monoxide, carbon dioxide, carbonic acid, carbonate, carbide, carborane, alkane**, carbonyl**, and organic ligand complexes of metals.
