Which product is formed by the bromination of cyclohexene?
1,2-dibromocyclohexane
Cyclohexene reacts with bromine in the same way and under the same conditions as any other alkene. 1,2-dibromocyclohexane is formed. The reaction is an example of electrophilic addition.
What happens when bromine reacts with cyclohexane?
Cyclohexane has no pi-unsaturation and is therefore not nucleophilic. It does not react with bromine unless energy in the form of light or heat is applied. In such a case a free-radical substitution reaction occurs. Cyclohexene is a typical alkene, and benzene and anisole are aromatic compounds.
What is the product of the reaction between cyclohexane and one mole of bromine water Br2 in the presence of UV light?
The reaction between hexene and bromine in presence of light gives 3-bromocyclohexene.
Why does cyclohexane not react with kmno4?
Why does cyclohexane not react with potassium permanganate? Cyclohexane though, is a saturated cyclic hydrocarbon. It does not have any unsaturated bonds or other chemical groups that are susceptible to electrophilic attack, so under normal conditions permanganate will not react with it.
What Colour is bromine in cyclohexane?
yellow-orange
Analysis of results – Trial results
| Halogen | Colour of upper organic layer after shaking with hydrocarbon solvent |
|---|---|
| bromine | aqueous: yellow-orange to colourless cyclohexane: colourless to pale yellow-orange |
| Iodine | aqueous: brown to colourless cyclohexane: colourless to pink/purple |
Why does bromine react more readily with cyclohexene than benzene?
Reaction with Bromine The increased reactivity compared to benzene is due to the lone pair of p-orbital electrons on the oxygen atom in the phenol group. The electron pair is delocalised into the ring structure, activating the ring.
What is the reaction between bromine and cyclohexane?
Investigating the Reaction Between Bromine and Cyclohexane. By adding bromine to a mixture of Cyclohexane and water, and placing. the mixture under a bright light and shaking from time to time, Hydrogen Bromide is formed. This reaction is shown below: [IMAGE]C6H12 + Br2 C6H11Br + HBr.
What are the conditions for bromination?
S E Ar (Electrophilic Aromatic Substitution) Sufficiently activated aromatic rings (ex. anilines and phenols) are readily brominated at or below room temperature.
Does cyclohexane react with bromine?
Cyclohexane has no pi-unsaturation and is therefore not nucleophilic. It does not react with bromine unless energy in the form of light or heat is applied. In such a case a free-radical substitution reaction occurs. Cyclohexene is a typical alkene, and benzene and anisole are aromatic compounds.
