What happen when chlorine reacts with bromine?
Electrons are shared between the chlorine atoms and the bromine atoms.
What effect does bromine have on moist indicator paper?
Bromine reacts with moisture on indicator paper to form hydrobromic acid, which changes the color of the indicator paper. This reaction typically results in a color change from blue to brown or red.
How can you tell whether a compound reacts with bromine?
You can test if a compound reacts with bromine by adding bromine water to the compound. If the compound reacts with bromine, the characteristic reddish-brown color of the bromine water will fade as it reacts with the compound. This reaction is often used to test for the presence of unsaturated bonds in organic compounds.
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.
Why does bromine water fade when testing for saturation?
Bromine water fades when testing for saturation because the bromine is decolorized by the unsaturated organic compounds present in the solution. This reaction occurs because the unsaturated compounds react with and break the bromine-bromine bond, causing the bromine solution to lose its color.
What changes in color occur when bromine or KMnO4 reacts with an alkene?
The purple KMnO4 is decolourise
What happen when chlorine reacts with bromine?
Electrons are shared between the chlorine atoms and the bromine atoms.
What changes in color occur when bromine or KMnO4 reacts with an alkane?
Bromine reacts with an alkane to produce a colorless solution, due to the formation of a colorless alkyl halide. On the other hand, potassium permanganate (KMnO4) reacts with an alkane to form a brown precipitate of manganese dioxide.
What happens when bromine water is used to test for unstauration?
The redish brown bromine color disappears by the addition of bromine to double bond.Br2 + H2C==CH-(CH2)n-CH3 ----> H2C(Br)--CH(Br)-(CH2)n-CH31-alkene ----> 1,2-dibroom-alkane

Why does when sodiumbromide reacts with chlorine the solution turns yellow?
The yellow color seen when sodium bromide reacts with chlorine is due to the formation of bromine, a reddish-brown liquid, which is a byproduct of the reaction. Bromine is responsible for the yellow color of the solution.
Which compounds will give you a positive bromine test?
Alkenes and alkynes will give a positive bromine test. The reddish-brown color of a bromine solution will be decolorized upon reaction with an alkene or alkyne due to the formation of a colorless dibromo compound.

Is The color of elemental bromine is orange-red a chemical property?
Yes, the color of elemental bromine being orange-red is a chemical property. Chemical properties describe how a substance reacts with other substances or changes chemically to form new substances, and in the case of elemental bromine, its distinct orange-red color is a characteristic that is specific to its chemical composition.
What is the colour of the bromine with the cyclohexene?
Bromine is reddish-brown in color. When it reacts with cyclohexene, the solution initially turns from red to colorless as the bromine adds across the double bond, forming a dibromo compound.
