What is the reaction of phenol with bromine water?
What is the reaction of phenol with bromine water?
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.
What is the products of bromination of phenol?
Phenol reacts with bromine in a presence of Carbon disulphide to form a mixture of o-bromophenol and p-bromophenol.
What is the bromination of phenol?
The action of bromine on phenol can be explained as. Phenol reacts with bromine water to give 2,4,6-tribromophenol. In water, ionisation is facilitated. Phenol gets ionised to form phenoxide ion, which is even better ortho-para directing.
Why does phenol give Tribromophenol on bromination with bromine water?
Phenol reacts with bromine water to give 2,4,6-tribromophenol. And Bromine ions are highly stabilized in ionic solvents.So the formation of strong o/p directing group and stabilization of Br+ enhances the formation of tribromophenol.
What is the action of a bromine water on phenol B bromine in acetic acid on anisole?
Explanation: Anisole undergo bromination with bromine in ethanoic acid (acetic acid) to form mixture of ortho and para bromo anisole. It is an example of electrophilic aromatic substitution reaction.
Why does phenol give Tribromophenol on bromination with bromine water while Monobromophenol in presence of CS2?
Phenol gives 2,4,6-tribromophenol when treated with bromine in aqueous solution but only o- and p-bromophenol in C Cl_(4) solution because. In CCl4, the other position of benzene rings are blocked by the solvent. In phenol, -OH group has activating and ortho, para-directing effect.
Why does phenol react with bromine?
The hydroxyl group is a strongly activating group and would make the aromatic ring easier to brominate. So, phenol undergoes bromination faster than benzene. Phenol reacts with bromine/water to give a tribrominated phenol.
What is the action of the following on phenol I Br2 in water bromine water II Br2 in carbon disulphide CS2 )?
a. Action of bromine in CS2 at low temperature on phenol: When phenol is treated with Br2 in non-polar solvent like CS2 or CCl4 or CHCl3 at 273 K, it forms a mixture of ortho- and para-Bromophenol isomers.
Which reagent is used in bromination of phenol?
So the reaction of the bromination of phenol by bromine water is the following: So the formation of $ 2,4,6 $ tribromophenol takes place with the help of the reagent called bromine water.
What is the major product of the reaction between phenol and bromine in the presence of CS2?
p-bromophenol
o and p-bromophenol.
Does phenol react with water?
You can recognise phenol because: It is fairly insoluble in water. It reacts with sodium hydroxide solution to give a colourless solution (and therefore must be acidic).
