In this compound, numbered from left to right, methyl is in the 3rd position, ethyl is in the 5th position, and the sum of the positions is 3 + 5 = 8; numbered from right to left, methyl is in the 6th position, ethyl is in the 4th position, and the sum of the positions is 6 + 4 = 10. Therefore, it should be numbered from left to right.
3. Write the name: Write the name of the substituent before the parent name. The substituents are listed after the preferred group according to the "order rule". The same substituents are combined, and the number is represented by the second and third grades. The positions are represented by Arabic numerals, and the numbers and Chinese characters are separated by "-". So the name of this compound is 5-ethyl-3-methyloctane.
In summary, the naming of 1-bromo-3-chloro-5-methyloctane is based on selecting the longest carbon chain as the main chain, reasonably numbering and writing the substituent and parent name according to the rules.

1 + - - 3 + - - 5 + - methylnaphthalene, which is an organic compound. Its physical properties are as follows:
Looking at its shape, it is mostly crystalline under normal circumstances. The color is often almost colorless, but it is slightly yellow due to impurities.
When it comes to the melting point, it is about a certain value range, and this value is of great significance to the transformation of its state. The characteristics of the melting point make the substance gradually melt from solid to liquid at a specific temperature. This temperature limit is relatively stable, which is an important basis for identifying the substance.

How is 1-bromo-3-chloro-5-methylbenzene prepared?
To prepare 1-alkyne-3-alkene-5-methylbenzene, the following method can be used.
First take an appropriate starting material, which needs to have a key group that can be derived from the target structure. With the common approach of organic synthesis, consider starting with compounds containing benzene rings with appropriate activity check points.
The first step may be to use a nucleophilic substitution reaction to introduce suitable substituents at specific positions in the benzene ring to prepare for the subsequent construction of alkynyl and alkenyl groups. When there are suitable substituents on the benzene ring, the alkynyl fragments can be introduced through metal-catalyzed reactions, such as palladium-catalyzed cross-coupling reactions. This process requires precise control of reaction conditions, such as temperature, catalyst dosage, reactant ratio, etc., to ensure that alkynyl groups can be selectively attached to the desired position.
Subsequently, the alkenyl group is constructed. Classic methods such as Wittig reaction or Horner-Wadsworth-Emmons reaction can be used to introduce alkenyl groups into the structure containing alkynyl groups and benzene rings. For example, select a suitable phosphorus ylide reagent or phosphonate reagent and react with the corresponding carbonyl compound to form the target alkenyl structure.
During the entire preparation process, the product of each reaction needs to be separated and purified to ensure the purity of the raw material in the next reaction. Common separation methods include distillation, column chromatography, etc. And to monitor the reaction process in real time, thin-layer chromatography (TLC), nuclear magnetic resonance (NMR) and other analytical techniques can be used to ensure that each step of the reaction proceeds as expected, and finally 1-alkyne-3-ene-5-methylbenzene is successfully prepared.

What are the chemical properties of 1-bromo-3-chloro-5-methylbenzene?
1 + - + ether + - + 3 + - + alkane + - + 5 + - + methylnaphthalene, which is an organic compound. It has the following chemical properties:
1. ** Substitution reaction **:
-methyl naphthalene can be substituted. If it interacts with halogen elements (such as chlorine) under light conditions, chlorine atoms can replace hydrogen atoms on methyl groups to form chlorinated methyl naphthalenes. This reaction mechanism is free radical substitution. Light prompts chlorine molecules to split into chlorine radicals. Chlorine radicals capture hydrogen atoms on methyl groups to form methyl radicals. Methyl radicals then react with chlorine to obtain chlorinated products.
-naphthalene rings can also be substituted. Because the naphthalene ring is aromatic, the electron cloud density is high, and the electrophilic reagent is easy to attack the naphthalene ring. For example, under the catalysis of ferric chloride, the electrophilic substitution reaction occurs with bromine, and the bromine atom is mainly substituted at the α position (the carbon atom site connected to the common edge in the naphthalene ring). Because the electron cloud density at the α position is higher than that at the β position, it is more susceptible to the attack of the electrophilic reagent.
2. ** Oxidation reaction **:
- Side chain methyl can be oxidized. If a strong oxidizing agent is used, such as acidic potassium permanganate solution, methyl can be oxidized to a carboxyl group to obtain the corresponding naphthalic acid. This reaction is a common method for introducing carboxyl groups to aromatic rings in organic synthesis
-naphthalene ring can also be oxidized under certain conditions. For example, under severe conditions, naphthalene ring can be oxidized to open the ring to form a compound containing multiple carboxyl groups. However, naphthalene ring is relatively stable, and strong oxidation conditions are required for oxidation to open the ring.
3. ** Addition reaction **:
-Although the naphthalene ring is aromatic, addition can occur under special conditions. For example, under high temperature and pressure and in the presence of a catalyst, an addition reaction can occur with hydrogen. When partially hydrogenated, partially hydrogenated naphthalene can be formed, and when continued hydrogenation can form decahydronaphthalene. This addition reaction can change the degree of unsaturation of the naphthalene ring, generate products with different saturation levels, and the physical and chemical properties of the products will also
