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.
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.
Phenol + 3Br2 = 2,4,6-tribromophenol + 3HBr Everything you need to know :) http://www.chemguide.co.uk/organicprops/phenol/ring.html
There is no reaction between phenol and sodium carbonate
The reaction between phenol and calcium hydroxide results in the formation of calcium phenolate and water. The chemical equation for this reaction is: C6H5OH (phenol) + Ca(OH)2 (calcium hydroxide) → Ca(C6H5O)2 (calcium phenolate) + H2O (water)

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.

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.

Yes, at room temperature bromine reacts with phenol and forms 2,4,6-tribromo phenol.
The reaction of phenol with Br2 proceeds through electrophilic aromatic substitution, where the bromine atom replaces a hydrogen atom on the benzene ring of phenol. This reaction is facilitated by the presence of the hydroxyl group on the phenol molecule, which activates the benzene ring towards electrophilic attack.
reaction b/w phenol and zinc yield benzene by reduction.
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.
In the reaction between phenol and sodium metal, sodium donates an electron to the oxygen atom in the phenol molecule, forming a sodium phenoxide salt and hydrogen gas. This process is a type of redox reaction where the sodium is oxidized and the phenol is reduced.
