Benzene 2 Bromo 4 Iodo 1 Methyl

What is the Chinese name of this compound?
"Tiangong Kaiwu" is an ancient scientific and technological masterpiece in our country, and the book has detailed descriptions of many substances. However, it is difficult to directly answer the name without knowing what this "compound" refers to.
"Tiangong Kaiwu" involves a lot of chemical related content, such as metal smelting, and there are records of the refining and related reactions of copper, iron, zinc and other metal compounds. For example, in zinc smelting, the book mentions that calamine (mainly composed of zinc carbonate) and charcoal are co-heated to obtain zinc through chemical reaction. Another example is pottery, clay is fired at high temperature, and complex compounds undergo physical and chemical changes, eventually forming pottery.
To know the exact Chinese name of this compound, more detailed information is required, such as the compound's properties, source, related chemical reactions, or specific chapters and paragraphs in the book, etc., in order to accurately infer its name based on "Tiangong Kaiwu" and related knowledge. It is difficult to give an accurate answer to such a general inquiry.

If you want to draw the simple formula of this compound, you can follow the method of "Tiangong Kaiwu" and describe it in ancient French.
First observe the structural characteristics of the compound. Detailed analysis of its atomic composition, chemical bonding and spatial arrangement. If it is an organic compound, when it is based on the carbon chain, it is outlined in an orderly manner according to the type and position of functional groups.
Take alkanes as an example. If it is pentane, the carbon chain contains five carbon atoms. According to the ancient formula, it can be written as: "Carbon is five, and it is named in the order. Each carbon is filled with hydrogen to make up for the lack of its valence bond, so that they are all tetravalent." Draw its simplified formula, with a straight line showing the carbon-carbon single bond, the end point and the fold point are carbon, the hydrogen atom is omitted, only the carbon chain skeleton is shown, and the simplified formula is "C-C-C-C-C".
If it is a compound containing functional groups, such as ethanol, there is a hydroxyl group (-OH). When remembering: "Carbon is two, connected to form a chain, one carbon is connected to a hydroxyl group, and the covalent bond is supplemented by hydrogen." Draw its simplified formula, first draw the carbon chain "C-C", and label "-OH" on its carbon side to form "C-C-OH". < Br >
Another example is olefins, taking ethylene as an example, containing carbon-carbon double bonds. It is said: "Carbon is two, connected by double bonds, and the residual valence bonds are filled with hydrogen." The simple formula is "C = C". Although the hydrogen atom has not been drawn in detail, it is known that each carbon is connected to dihydrogen to be full tetravalent.
When drawing, it is necessary to strictly abide by the rules of valence bonds, carbon must be tetravalent, hydrogen monovalent, oxygen divalent, etc. And according to the atomic connection order and the spatial relationship, it is accurately depicted, so as to present the simplest and clearer structure of the compound, so that people can see its structural characteristics at a glance.

This compound has a variety of physical properties. Its color state or solid state, often crystalline, uniform in quality and regular in shape, just like the "Tiangong Kaiwu" said "where the crystal is crystalline, its shape is neat". Part of it may also be liquid, with a clear texture and flowing, as described in the book "flowing but not stagnant, clear and can be learned".
When it comes to melting points, there are differences in height. Those with high melting points need to be roasted in a hot fire before they can melt, just like the high melting point of the metal involved in "real gold is not afraid of fire refining"; those with low melting points turn into fluids when they are slightly heated, just like spring snow melts when it is warm. In terms of boiling point, it also varies depending on the characteristics of the compound. When it is high temperature, it turns into a gaseous state and rises in the air, such as "the rise of clouds and fog, the transformation of gas".
The density of the compound is different. The heavy ones sink to the bottom of the water, like gold and stone falling into the abyss; the light ones float on the water, just like wood floating in the river. The solubility is also diverse. In some solvents, it can be quickly dissolved to form a uniform solution, just like salt melting in water; in other solvents, it is insoluble or insoluble, just like the mutual exclusion of oil and water.
Its conductivity is also divided into different cases. Under specific conditions, it may be able to conduct electricity, such as the conduction of metal; or the insulation is not conductive, like the resistance of porcelain stone. The thermal conductivity also varies. Those with good thermal conductivity have rapid heat transfer, such as copper and iron; those with poor thermal conductivity have slow heating, such as wood and stone. Such various physical properties are of key significance in the identification and application of substances.

This compound may be able to undergo many chemical reactions, and let me tell you one by one.
One, or a substitution reaction may occur. If the compound contains specific functional groups, such as halogen atoms of halogenated hydrocarbons, hydroxyl groups of alcohols, etc. When encountering suitable reagents, such as halogenated hydrocarbons in basic aqueous solutions, halogen atoms can be replaced by hydroxyl groups, just like halogenated alkanes and sodium hydroxide aqueous solutions are co-heated, the halogen atoms leave, and the hydroxyl groups connect to form corresponding alcohols. This is one of the common substitution reaction pathways.
Second, addition reactions are also possible. If there are unsaturated bonds such as carbon-carbon double bonds and carbon-carbon triple bonds in the compound. Taking alkenes as an example, they can be added with hydrogen, halogen elements, hydrogen halides, etc. For example, when ethylene reacts with bromine water, the carbon-carbon double bond is opened, and the bromine atom is added to the two carbon atoms, respectively, to form 1,2-dibromoethane. This process converts the double bond into a single bond, increasing the number of atomic connections.
Third, oxidation reactions may occur. If it contains oxidizable functional groups, such as alcohol hydroxyl groups, under the action of suitable oxidants, primary alcohols can be oxidized to aldehyde, which can then be reoxidized to carboxylic acids. Taking ethanol as an example, it reacts with oxygen under the catalysis of copper or silver to form acetaldehyde, which can be further oxidized to give acetic acid. If the compound contains aldehyde groups, it can also be oxidized to carboxylic acids by various oxidants, which are all manifestations of oxidation reactions.
Fourth, esterification reactions are also possible reactions. If there are both hydroxyl and carboxyl groups in the compound, under the catalysis of concentrated sulfuric acid and heating conditions, the hydroxyl and carboxyl groups can undergo esterification reaction to form esters and water. This reaction is often seen in organic synthesis, and the resulting esters often have a special fragrance.
Fifth, the hydrolysis reaction cannot be ignored. If it is an ester compound, hydrolysis can occur under the catalysis of acids or bases. When acidic hydrolysis, corresponding carboxylic acids and alcohols are formed; when basic hydrolysis, carboxylic salts and alcohols are formed. For example, ethyl acetate is hydrolyzed in sodium hydroxide solution to form sodium acetate and ethanol. This process breaks the ester bond and reacts with water.
In short, this compound exhibits rich chemical properties according to the functional groups contained in its structure or the many chemical reactions mentioned above.
