What colour is bromine dissolved in cyclohexane?
Bromine dissolved in cyclohexane appears orange in color.
What happens when bromine water is added to paraffin?
When bromine water is added to paraffin, no visible reaction occurs. Paraffin is a non-reactive hydrocarbon compound, so it does not undergo a chemical reaction with bromine. The bromine remains as a colored solution with no change in the paraffin.
What happens between bromine and water when you add hydrochloric acid?
When hydrochloric acid is added to a mixture of bromine and water, bromine will react with hydrochloric acid to form hydrogen bromide and hypobromous acid. This reaction can then proceed further to form bromine chloride and bromine, depending on the conditions present.
What happens when bromine water is added to oil?
When bromine water is added to oil, if the oil contains unsaturated bonds, the reddish-brown color of the bromine water will be reduced as the bromine molecules add across the double bonds in a chemical reaction called bromination. This reaction is used to test for the presence of unsaturation in organic compounds like alkenes or alkynes.
What happens when bromine is added to water?
When bromine is added to water, it reacts to form hypobromous acid (HBrO) and hydrobromic acid (HBr). This can further dissociate to form bromide ions (Br-) and hypobromite ions (OBr-). The overall reaction can be summarized as follows: Br2 + H2O → HBrO + HBr
What happens when the bromine solution is first added to cyclohexane?
At room temperature, the halogens like bromine don't react with cyclohexane. Hence the dark brown color of the bromine water remains. When heated, the -H atoms are replaced with -Br(substitution reaction).
What colour is bromine dissolved in cyclohexane?
Bromine dissolved in cyclohexane appears orange in color.
What is the chemical formula for cyclohexane and bromine and water?
The chemical formula for cyclohexane is C6H12, for bromine it is Br2, and for water it is H2O.
What happens when bromine water is added to phenol?
tribromophenol is formed.
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.
Why does Br2 dissolve in cyclohexane and not in water?
Bromine (Br2) dissolves in cyclohexane due to its nonpolar nature, which is similar to cyclohexane's nonpolar composition. In contrast, bromine does not dissolve in water because water is a polar solvent and bromine is nonpolar, leading to poor solubility due to the mismatch in polarity.
What happens when bromine is added to cyclohexene?
When bromine is added to cyclohexene, a halogenation reaction occurs where the double bond of cyclohexene is broken and bromine adds to the carbon atoms that used to be part of the double bond. This forms a dibrominated product.
What happens when bromine water is added to paraffin?
When bromine water is added to paraffin, no visible reaction occurs. Paraffin is a non-reactive hydrocarbon compound, so it does not undergo a chemical reaction with bromine. The bromine remains as a colored solution with no change in the paraffin.
What is the mechanism for the reaction between bromine and cyclohexane and state the conditions favor the reaction?
The reaction between bromine and cyclohexane involves substitution of a hydrogen atom in cyclohexane with a bromine atom, forming bromocyclohexane. This reaction is a free-radical substitution reaction. Conditions favoring the reaction include the presence of light or heat to initiate the free radical formation and the use of a radical initiator such as peroxides.
What happens when a drop of water is added to calcium carbide in the presence of bromine solution?
Probable tetrabromoethane is formed.
What happens when bromine water reacts with alkenes?
Bromine water reacts with alkenes through an electrophilic addition reaction where the pi bond of the alkene breaks, and bromine atoms are added to the carbon atoms. This reaction results in the decolorization of the bromine water, changing it from orange to colorless.
What happens when 1 drop of bromine is added to vegetable oil?
When 1 drop of bromine is added to vegetable oil, a chemical reaction occurs where the bromine reacts with the unsaturated fats in the oil. This reaction causes the bromine to decolorize, turning from reddish-brown to colorless. This change is a test for the presence of unsaturated fats in the vegetable oil.
