Does toluene react with bromine?

Benzene and toluene do not react with bromine in the absence of a catalyst. Phenol is more reactive due to the presence of an electron donating hydroxyl group and reacts with bromine by a substitution reaction forming hydrogen bromide gas.

Does bromine water react with toluene?

When toluene and a bromine solution react, there is no reaction. That is, the solution turns a yellow/brown colour, the same as the bromine solution.

Which can Decolourise bromine water?

Solution: Butyne, Ethene and Hexyne, all can decolourise bromine water.

What happens when toluene is treated with bromine?

Toluene reacts with bromine in the presence of light to give benzyl bromide, while in the presence of FeBr3, it gives p−bromotoluene.

What compounds would Decolourise bromine?

Ethene, butyne, and hexyne can decolourize bromine water.

Which compounds Cannot Decolourise bromine water?

Explanation: Unsaturated hydrocarbons (cooking oil) discolor the reddish-brown color of bromine water, while saturated hydrocarbons cannot discolor. . The alkanes are stable and in the nonexistence of catalysts, they can not decompose the red-brown bromine.

Does benzene Decolourise bromine water?

Benzene does not decolourise bromine water.

Which can Decolourise bromine water?

Solution: Butyne, Ethene and Hexyne, all can decolourise bromine water.

Which of the following hydrocarbon can Decolourise bromine water?

C6H12 (Hexene) and C6H10 (Hexyne or Cyclohexene ) are the hydrocarbons which can decolourize bromine water, as they are unsaturated.

Why does benzene not Decolourise bromine?

Benzene molecule is unsaturated but it does not undergo electrophillic addition reaction because saturating the carbon-carbon bonds destroys the delocalized pi-cloud and as we know that this delocalized pi-structure is very stable. So due to this benzene does not decolourises bromine water.

Does acetylene Decolourise bromine water?

Acetylene is known as ethyne. It is an unsaturated compound and it decolorizes bromine water as triple bonds are present in it which is a condition for additional reaction of bromine water.

Do aromatic compounds react with bromine water?

properties accordingly in electrophilic substitution reactions of substituted aromatic compounds. Worked examples: Q1) Phenylamine, C6H5NH2 can react with bromine in an electrophilic substitution reaction.

Does benzene react readily with bromine water?

Low Reactivity

If [math] double bonds were present then benzene would react in a similar way to alkenes, decolourising bromine water. However this does not happen as benzene doesn’t react with bromine. Benzene cannot react in any other electrophilic addition reactions.

Does benzene react with water?

Benzene is insoluble in water according to this definition. Benzene is a symmetrical compound and thus it has zero dipole moment and is non-polar, while water is a polar compound possessing dipole moment. … Hence, it is insoluble in water.

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.

How does phenol react with bromine water?

When phenol reacts with bromine water 2,4,6- tribromophenol is formed. Bromine water is decolourises and a white precipitate is formed.

Why does benzene react with bromine?

Benzene reacts with chlorine or bromine in the presence of a catalyst, replacing one of the hydrogen atoms on the ring by a chlorine or bromine atom. … These compounds act as the catalyst and behave exactly like aluminium chloride, AlCl3, or aluminium bromide, AlBr3, in these reactions.

What is bromine water test?

The bromine water test is a qualitative test, used to identify the alkene or alkane functional groups present in the compound. Alkene groups react with bromine water in the dark condition and undergo an addition reaction, to give a decolourized solution.

Can phenol react with Ethanoyl chloride?

Phenol reacts with ethanoyl chloride at room temperature, although the reaction isn’t as fast as the one between ethanoyl chloride and an alcohol. Phenyl ethanoate is formed together with hydrogen chloride gas.

When phenol reacts with bromine water in presence of polar solvent it produces?

2,4,6 -tribromophenol.

What kind of reaction is involved in bromination of phenol?

Action of bromine on phenol in the presence of different catalysts. When bromine water is added to phenol, white ppt of 2,4,6-tribromophenol appears. This is an electrophilic substitution reaction.
