Common questions

How does cyclohexane react with bromine water?

How does cyclohexane react with bromine water?

If bromine water is put into a glass of cycloHEXANE, the solution will turn the yellowish/orange colour of the bromine water, as no reaction takes place, whereas if it is put in cycloHEXENE, the solution will go colourless, as the bromine bonds with the cyclohexene.

What is the equation for the reaction of cyclohexene with bromine?

So C6H10 + Br2 –> C6H10Br2. Not 100% sure though. Both of you are technically right – regarding the state of bromine and the actual equation.

What is the formula for bromine water?

Br2
Bromine water, also called Bromide bromate solution or Bromine solution with the chemical formula Br2. The molecular weight of bromine water is 159.81 and the density is 1.307 g/mL. Bromine water is a yellow mixture solution with high oxidizing property, prepared by dissolving diatomic bromine (Br2) in water (H2O).

Does cyclohexane give bromine water test?

Even though benzene has unsaturated bonds, they are stable and thus will not react with bromine water solution and thus no decolourisation of bromine water. In dark conditions, cyclohexane does not show any reaction with bromine water.

What happens when hexene is mixed with bromine?

Bromine is much more soluble in, and reacts with hexene; so if you shake the two together, the bromine will move into, and react with the double bond on the hexene, making dibromohexane which will float on the clarifide water.

Do alkanes react with bromine water?

Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot.

What type of reaction is ethene and bromine?

Mechanism. The reaction is an example of electrophilic addition. The bromine is a very “polarizable” molecule and the approaching pi bond in the ethene induces a dipole in the bromine molecule.

Why does cyclohexene Decolorize bromine?

Why does an alkene Decolourise bromine water? Bromine breaks the double bond of cyclohexene (and all alkenes), making the molecular structure change and therefore the molecule’s properties change.

Does phenol give bromine water test?

If bromine water is added to a solution of phenol in water, the bromine water is decolorized and a white precipitate is formed which smells of antiseptic. The precipitate is 2,4,6-tribromophenol. Notice the multiple substitution around the ring – into all the activated positions.

What is the color of bromine in water?

Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene.

What happens when alkanes are added to bromine water?

Alkanes and alkenes tend to be colourless. So, when bromine water is added to an alkane or alkene and mixed well, initially the mixture turns a red-brown colour due to the bromine. Alkanes are far less reactive than alkenes and will only react with bromine water in the presence of UV light.

Does phenol Decolourise bromine water?

Hint: When bromine water is added to a solution of phenol in water, the bromine water is decolourised and a white precipitate is formed which smells of antiseptic. We know that the reaction of phenol and water with bromine is known as bromination of phenol.

What is the equation for the reaction between cyclohexene and bromine water?

The displacement of a bromine atom by an amine is a substituion reaction. The chemical reaction is:C6H10 + Br2 = C6H8Br2 What is the equation for the reaction between cyclohexene and bromine water? js992 said: C6H10 + Br2 +H2O —> C6H10BrOH + BrOH.

Is it safe to mix bromine with cyclohexane?

Bromine is highly toxic and reactive. Use care. Both cyclohexane and cyclohexene are very flammable. Keep away from flames. Cyclohexene and cyclohexane have an irritating odor. Dichloromethane is a cancer suspect agent. Fill 1 cylinder 1/2 full with cyclohexane and fill the other 1/2 full with cyclohexene.

Which is correct, cyclohexene aq or Broh AQ?

BrOH (aq) is also acceptable but it complicates your chemical equations so you shouldn’t use this. For context (AFAIK), the HSC first used BrOH (aq) but then later also allowed Br2 (aq) to avoid confusion. Again, do what you are comfortable with. 3. Cyclohexene (C6H10), Cyclohexane (C6H12) are correct. 4.

What is the equation of ethane and bromine?

The balanced equation of ethane and bromine is (by double displacement): C2H6 + Br2 –> C2H5Br + HBr Reaction equation of lithium and bromine? 2Li + Br2 ——-> 2 LiBr Explain why the addition of bromine to trans-cinnamic acid takes place more slowly than the addition of bromine to a normal alkene like 3-hexene or cyclohexane?
