What are the physical properties of 3-chlorobromobenzene?
3-% fluoric acid is strong and strong, and has a physical property that cannot be ignored.
The liquid of its color, under normal conditions, is flowing, similar to water and has a slightly low nature. It is pungent and escapes, and it is inconvenient to smell. It is even related to breathing. Its boiling temperature is low, > 19.5 ° C, and it melts slightly. It is scattered in the air.
Furthermore, the density of 3-% fluoric acid is slightly higher in water, 1.15 grams per cubic centimeter. This density characteristic makes it settle in water rather than float on the surface. And because of its solution, it has good performance. Because of the fluoric acid in the water part of the water, the fluoride is produced, and the two can be charged, so it can be damaged.
However, the most terrifying thing is the strong decay. The degree of decay is 3%, and the general object is connected, which can make it suffer. If the glass meets, the main component of the glass is silica, which causes the glass surface to invade and change the appearance. If the skin is accidentally connected, it will quickly enter the deep muscle, and it will feel a slight tingling at the beginning or at the beginning. The pain is not intense, and the damage to the body is very deep.

What are the chemical properties of 3-chlorobromobenzene?
3-Bromopentane is an organic compound with many chemical properties.
First, nucleophilic substitution reaction. Because the bromine atom in the molecule is a good leaving group, it is vulnerable to nucleophilic attack. If it is co-heated with sodium hydroxide aqueous solution, the hydroxyl group will replace the bromine atom as a nucleophilic reagent to generate 3-pentanol. The reaction mechanism is $S_ {N} 2 $or $S_ {N} 1 $, depending on the reaction conditions. If the reagent has strong nucleophilicity and small solvent polarity, it tends to be $S_ {N} 2 $; if the reagent has weak nucleophilicity and large solvent polarity, $S_ {N} 1 $is more likely.
Second, eliminate the reaction. Under alkaline conditions such as potassium hydroxide alcohol solution, 3-bromopentane will undergo elimination reaction, and the bromine atom will be removed together with the hydrogen atom on the adjacent carbon atom to form an olefin. According to Zaitsev's rule, the main product is 2-pentene.
Third, react with metals. 3-bromopentane can react with metals such as magnesium in anhydrous ether and other solvents to form Grignard reagents. Grignard reagents are extremely reactive and can react with aldons, ketones, carbon dioxide and other substances. They are key reagents for building carbon-carbon bonds in organic synthesis.
Fourth, reduction reaction. Under the action of specific reducing agents such as lithium aluminum hydride, bromine atoms in 3-bromopentane can be replaced by hydrogen atoms to form pentane.
In short, 3-bromopentane is chemically active due to its functional group containing bromine atoms, and is widely used in the field of organic synthesis. It can prepare a variety of organic compounds through various reactions.

What are the synthesis methods of 3-chlorobromobenzene?
There are several ways to synthesize 3-bromopentane. The common ones are briefly described.
First, pentanol and hydrobromic acid are used as raw materials and prepared by substitution reaction. In pentanol, the hydroxyl group is an active group, and the hydrobromic acid provides bromine ions. Mixing the two, under appropriate conditions, the hydroxyl group of pentanol is replaced by bromine ions, and 3-bromopentane is obtained. The reaction formula is roughly: $C_ {5} H_ {11} OH + HBr\ longrightarrow C_ {5} H_ {11} Br + H_ {2} O $. When reacting, pay attention to the control of temperature. If the temperature is too high or too low, it can affect the rate and yield of the reaction. Usually, moderate heating and the addition of a catalyst such as sulfuric acid can promote the reaction.
Second, it is obtained by the addition reaction of pentene and hydrogen bromide. Pentene has unsaturated double bonds and is active in nature. Hydrogen and bromine atoms of hydrogen bromide are added to the carbon atoms at both ends of the pentene double bond. Taking 3-pentene as an example, the addition of 3-pentene to hydrogen bromide follows the Markov rule or the anti-Markov rule (depending on the reaction conditions). If the reaction tends to be anti-Markov addition in the presence of peroxide, 3-bromopentane can be generated. The reaction formula is: $CH_ {3} CH = CHCH_ {2} CH_ {3} + HBr\ xrightarrow [] {peroxide} CH_ {3} CH_ {2} CHBrCH_ {2} CH_ {3} $. This reaction condition is relatively mild, but the amount of peroxide and the dryness of the reaction environment also have an important influence on the reaction result.
Third, using pentane as the starting material, the bromopentane mixture is first halogenated, and then 3-bromopentane is obtained by separation and purification. Free radical substitution reaction occurs between pentane and bromine under light or heating conditions. Although the product is a mixture of various bromopentane, pure 3-bromopentane can be obtained by fractionation, extraction and other separation methods. Although this approach is a little complicated, the raw material pentane is relatively easy to obtain, which is a feasible method.

What are the effects of 3-chlorobromobenzene on the environment and humans?
"Mercury, commonly known as mercury, is like water and resembles silver, hence the name." Mercury is a highly toxic substance that is harmful to both the environment and the human body.
In terms of the environment, if mercury escapes between heaven and earth and enters rivers, lakes and seas, it will be taken up by aquatic organisms. It gradually accumulates in the body of organisms and is transmitted through the food chain layer by layer, and the effect of enrichment increases sharply. For example, tiny plankton eat mercury-containing particles, small fish eat plankton, and big fish eat small fish. The concentration of mercury in the body of the big fish is much higher than that of the surrounding water. Once the mercury pollution in the water body is serious, a large number of aquatic animals and plants will die, the ecological balance will be destroyed, and the vitality of the water will be lost. And mercury can volatilize into the atmosphere, float with the air flow, fall in distant soil and water bodies, causing a wide range of pollution.
The harm to the human body should not be underestimated. If a person inhales mercury vapor through breathing, or eats mercury-containing food by mistake, mercury enters the human body. Mercury can damage the human nervous system, cause cognitive impairment, memory loss, emotional instability, and severe convulsions and coma. It also hurts the kidneys, interferes with the normal metabolism and excretion of the kidneys, and causes abnormal kidney function, resulting in proteinuria, edema, etc. If pregnant women are exposed to mercury, mercury can endanger the fetus through the placenta, causing fetal malformation and mental retardation. Therefore, our generation should be well aware of the hazards of mercury, and in industrial production, daily use, and other aspects, strict prevention and control should be taken to prevent the spread of mercury indiscriminately, in order to protect the environment and human well-being.
