Are bromobenzene and NaOH miscible together? and a chemistry problem.

Chemistry questions. A total of 5mol of chlorine is consumed.

Ethylene is a carbon-carbon double bond, and only one bond is broken in the addition reaction.

Becoming ch2cl-ch2cl consumes 1mol of chlorine.

The principle of substitution reaction is the position of the chlorine atom replacing the hydrogen atom, and there are 4 hydrogen atoms in CH2Cl-CH2Cl.

Therefore, 4mol of chlorine gas needs to be consumed.

The equation is. ch2cl-ch2cl+cl-cl→ch2cl-chcl2+hcl

ch2cl-chcl2+cl-cl chcl2-chcl2+hclchcl2-chcl2+cl-cl chcl2-ccl3+hclchcl2-ccl3+cl-cl ccl3-ccl3+hcl each chlorine molecule provides only one position where a chlorine atom is used to replace a hydrogen atom.

Bromobenzene and sodium hydroxide solutions are immiscible.

This is the problem of lab-made bromobenzene:

Generally speaking, bromobenzene does not react with sodium hydroxide, and due to the influence of the benzene ring, the bromine atom on the benzene ring is very inactive and difficult to replace. It is by taking advantage of this that the bromine element mixed in bromobenzene is removed with a NaOH solution. Bromobenzene is an organic matter, and sodium hydroxide solution is an inorganic solution, the two are not miscible and will be stratified after mixing.

That's what the high school years are asked for. But when you go to college, you will know that they can be reactive, but the conditions are more demanding.

To react, how to dissolve?

Bromine reacts with sodium hydroxide to produce the corresponding sodium bromide and water.

Under certain conditions, bromobenzene and NaOH can react

Bromobenzene and NaOH undergo substitution reactions at high temperature, high pressure and Cu as catalysts.

The chemical equation is as follows:

C6H5BR+H2O===NaOH and Cu, high temperature, high pressure) C6H5OH+HBR

Bromobenzene and sodium hydroxide can have substitution reactions, but the reaction rate is relatively slow, and it is generally not considered in high schools. Bromobenzene and sodium hydroxide undergo substitution reactions under the disturbance of high temperature, high pressure and Cu as catalysts. The chemical equation reflected is C6H5BR H2O===NaOH and Cu, high temperature, high pressure) C6H5OH HBR.

Bromine plum, benzene.

Bromobenzene is an organic compound, a colorless, oily liquid with the smell of benzene. Insoluble in water, soluble in methanol, ether, acetone and other organic solvents. In the chemical industry, it is mainly used for solvents, analytical reagents and organic synthesis.

Bromobenzene is obtained by the reaction of benzene with bromine. First, iron powder and stuffy benzene are added to the reactor, liquid bromine is slowly added under stirring, and after addition, the reaction is kept at 70-80 for 1h, and the crude product obtained is washed with water and 5% sodium hydroxide solution, and then stratified, distilled, dried, filtered, and finally often fractionated, and 155-157 fractions are taken to obtain the finished product.

4. The chemical formula of sodium hydroxide is NaOH, commonly known as caustic soda, caustic soda, caustic soda, which is a strong alkali with strong corrosiveness, generally in the form of flakes or granules, easily soluble in water (exothermic when dissolved in water) and forms an alkaline solution, and deliquescent, easy to absorb water vapor (deliquescent) and carbon dioxide (deterioration) in the air.

Generally, it is non-reactive, but the substitution reaction occurs under the conditions of high temperature and high pressure and copper metal as a catalyst;

Equation: One mole of bromobenzene plus two moles of sodium hydroxide to produce one mole of sodium phenol, sodium bromide and water;

Bromobenzene, organic compound, colorless oily liquid, with benzene odor, insoluble in water, soluble in methanol, ether, acetone and other organic solvents, mainly used in chemical industry, solvents, analytical reagents and organic synthesis;

Answer]: Solution: Tert-butyl bromide undergoes a single-molecule nucleophilic substitution reaction in the NaOH water perturbation solution, and the reaction rate is not related to the NaOH concentration, because the hydrolysis rate of tert-butyl bromide in the same concentration of NaOH aqueous solution is the same.

The tribromotoluene and sodium hydroxide reaction is a classic acid-base reaction, also known as acid-base neutralization reaction. In this reaction, tribromotoluene acts as an organic acid and sodium hydroxide acts as a base, and when they react, salt and water are produced. The specific reaction equation is as follows:

c7h3br3o + naoh → nac7h3br3o + h2o

In this reaction, the carboxyl group (-COOH) in tribromotoluene reacts with the hydroxide group (-OH) in sodium hydroxide to produce salt (NaC7H3BR3O) and water (H2O). Since hydrogen ions (H+) and hydroxide ions (-OH) combine to form water, this reaction is also known as acid-base neutralization reaction.

In the experiment, sodium hydroxide solution can be added to the bowl, and tribromine solution can be gradually added to make noise in the morning. The reaction occurs immediately, producing a large amount of gas (carbon dioxide) and heat. Therefore, it is necessary to pay attention to safety, adequate ventilation and protective measures when performing this reaction in the laboratory.

In summary, the tribromotoluene and sodium hydroxide reaction is a classic acid-base neutralization reaction, producing salt and water. Safety needs to be taken into account when doing it in the laboratory.

The reaction of tribromotoluene and sodium hydroxide can undergo SNAR substitution reaction to produce two products, tribromo-p--creluol and hypobromo-p--cresphenol.

The reaction mechanism is as follows: firstly, the sodium hydroxide beam roll will cause a halogen atom in tribromotoluene to undergo a negative charge effect, and the intermediate arbr2- is formed, which is a nucleophile. The intermediate then attacks the more electrophilic aromatic ring carbon atom in the tribromotoluene molecule to form a conjugated intermediate.

This intermediate is then attacked by sodium hydroxide, which again decharges one of the halogen atoms to form hypobromo-p-toluenol. At the same time, during the reaction, some intermediates disappear to form tribromo-p-toluenol.

The general reaction equation is as follows:

c6h2br3cl + naoh → c6h2br2oh + c6h2br3oh + nacl

Among them, C6H2BR2OH is the second beat bromide-p-to-toluphenol, and C6H2br3OH is tribromo-p-crelufine.

The reaction of tribromotoluene and sodium hydroxide produces phenol and tribromomethyl thane. The reaction equation is as follows:

c6h2br3cl + 4 naoh → cbr3oh + c6h5oh + 4 nacl

Among them, C6H2BR3Cl is tribromotoluene, NaOH is sodium hydroxide, CBR3OH is tribromomethane, C6H5OH is phenol, and NaCl is sodium chloride.

This is an alkaline hydrolysis reaction, and sodium hydroxide is an alkaline reagent that will decompose tribromotoluene into phenol and tribromomethylthane. During the reaction, it is necessary to pay attention to the corrosion resistance of the reaction vessel, because sodium hydroxide is a strong alkali, and the container needs to choose a material that can withstand strong alkali.
