Yes, at room temperature bromine reacts with phenol and forms 2,4,6-tribromo phenol.
Phenol is not dissolved in a sodium hydroxide solution; having the characteristics of a weak acid phenol react with NaOH.
A positive Lucas test on phenol would indicate that phenol is a strong enough acid to react with Lucas reagent (a mixture of concentrated hydrochloric acid and zinc chloride) to form a cloudy solution or a precipitate. This reaction distinguishes phenol from other alcohols that do not react with the Lucas reagent.
Now this is a benzene ring with a Hydroxide on top, and a bromide on bottom; the p means opposite side
Phenol does not react with PCl5 under room temperature and pressure because the hydroxyl group (-OH) on phenol is not a strong enough nucleophile to displace the chloride ions in PCl5. Additionally, the lone pairs on the oxygen in phenol are occupied with electron delocalization within the benzene ring, making them less available for nucleophilic attack.
There need to be more details provided to answer this question. If you are referring to the white precipitate that is produced in the bromination of phenol which is also known as phenylamine by adding bromine(aq) to phenol or phenylamine then the answer is 2,4,6-tribromophenol or it can be written as 2,4,6-tribromophenylamine.
The ferric chloride test: Ethanol does not react with ferric chloride, while phenol forms a purple color when mixed with ferric chloride. The bromine water test: Ethanol does not react with bromine water, while phenol decolorizes bromine water due to its reducing properties.
The reaction product of bromine and phenol is 2,4,6-tribromophenol. In this reaction, the bromine replaces the hydrogen atoms on the phenol ring to form a tribrominated product.
Phenol + 3Br2 = 2,4,6-tribromophenol + 3HBr Everything you need to know :) http://www.chemguide.co.uk/organicprops/phenol/ring.html
In the bromination of phenol, the mechanism involves the substitution of a hydrogen atom on the phenol ring with a bromine atom. This reaction is typically carried out in the presence of a brominating agent, such as bromine or a bromine-containing compound, under acidic conditions. The bromine atom replaces the hydrogen atom on the phenol ring, resulting in the formation of bromophenol.
The hydroxyl group in phenol is an activating ortho/para director, but has some slight steric hindrance too ortho position substitution. Therefore, the predominant product of reaction between phenol and bromine will be 4-bromophenol, if reaction conditions are carefully controlled. With excess bromine, di- and tri-bromo phenols will be formed.
The substitution reactions of phenol are easier than benzene, phenol directly reacts with bromine and gives tribromo phenol while benzene requires FeCl3 as a catalyst and gives mono bromo phenol.
tribromophenol is formed.
Yes
Ethanol does not react with bromine.
The reaction between phenol and bromine water results in the substitution of a hydrogen atom on the benzene ring with a bromine atom. This forms bromophenol as the product. The reaction is a bromination reaction and the presence of phenol's hydroxyl group activates the benzene ring towards electrophilic substitution.
Without phenol, the bromine would not have a stable medium for the reaction, leading to a lack of suitable environment for the reaction to occur. Phenol acts as a catalyst in this reaction by providing a stable medium for the formation of the bromine products.
what is the chemical equation when phenol react with hydrochloric acid
