What causes the decolourization in the reaction mixture of ethylbenzene and bromine and dichloromethane?
H3CC(H2)-Ph + Br2 (brown) ---> H3CC(H)(Br)-Ph + HBr (colorless gas) This reaction has radical nature, and is catalyzed by peroxides, such as benzoyl peroxide. It proceeds fast at 80°C, slower at RT. In general, alpha position of alkylarenes (the carbon that is next to aromatic ring) is quite succeptible to all kinds of reactions.

What substance turns dichloromethane to a violet color?
Bromine water turns dichloromethane to a violet color.
What type of reaction is it when methane reacts with bromine?
The reaction between methane and bromine is a substitution reaction, specifically a halogenation reaction. In this reaction, one or more hydrogen atoms in methane are replaced by bromine atoms to form bromomethane.
What forms from the reaction of bromine with acetophenone?
The reaction of bromine with acetophenone can yield several products, depending on reaction conditions. One common product is α-brominated acetophenone, where bromine adds to the alpha carbon of the carbonyl group. This reaction can also lead to dibrominated acetophenone if excess bromine is used.
What happens when chlorine is added bromine ions?
When chlorine is added to a solution containing bromine ions, the chlorine will react with the bromine ions to form a mixture of chlorine and bromine compounds, such as bromine chloride. This reaction is a redox reaction where chlorine is reduced and bromine is oxidized.
In the reaction between bromine and sodium a bromine atom gains an electron and forms the bromine ion Br. what happens to bromine?
In the reaction, bromine gains an electron and forms a bromide ion (Br-). This results in a decrease in the oxidation state of the bromine atom from 0 to -1.
What is the equation reaction for cyclohexene bromine in dichloromethane?
The reaction between cyclohexene and bromine in dichloromethane results in the addition of bromine across the double bond in cyclohexene to form 1,2-dibromocyclohexane. The balanced chemical equation can be represented as: C6H10 + Br2 → C6H10Br2.
What substance turns dichloromethane to a violet color?
Bromine water turns dichloromethane to a violet color.
How do you identify this type of reaction?
During the elimination reactions of saturated organic compounds double bond (Alkene) or triple bond (Alkyne) is formed to check them add Bromine solution to reaction mixture the decolourization of bromine confirms the elimination reaction
What is function of CCl4?
Bromine is nonpolar and needs a nonpolar solvent to do the bromination reaction. CCl4 is a heavy, nonpolar solvent that dissolves the heavy Br2 molecule. With lighter nonpolar solvents such as hexane, the high density Bromine settles out.
Does pentene decolourise bromine solution?
Pentene is an unstaturdated hydrocarbon (One that does not have many possible side branches) It reacts readily with halogens to form new substances. In this case, bromine reacts with pentene in an addition reaction, this changes pentene into 1,1-dibromopentane. Thus, removing bromine from the solution, hence the distinct orange color is removed.

Does bromine react to sodium?
Yes, bromine reacts with sodium to form sodium bromide. This reaction is a displacement reaction where bromine replaces another element in a compound.
