What happens when phenol reacts with bromine water?
Phenol produces a white precipitate of 2,4,6-tribromophenolol when combined with excess bromine water. In order to have 2,4,6-tribromophenol, phenol reacts with bromine water. The ionisation is promoted in liquids. To form phenoxide ion, phenol is ionised, which is much stronger for directing ortho-para.
When phenol is treated with bromine water it results in the formation of?
The reaction of phenol with bromine water results in the formation of polyhalogen derivatives.
What is the product when phenol reacts with bromine in ethanol?
When Phenol reacts with bromine water it results in formation of white precipitate of tri-bromo phenol. In aliphatic compounds of alcohol has no reaction with bromine water. So here ethanol does not react with bromine water.
Does phenol give bromine water test?
Organic compounds like phenols, alkenes, acetyl compounds and anilines will readily undergo bromine water tests.
What is product obtained when phenol reacts with bromine water bromine and cs2?
1 Answer. (i) When the reaction is carried out in solvents of low polarity such as CHCl3 or CS2 and at low temperature, monobromophenols are formed. (ii) When phenol is treated with bromine water, 2,4,6- tribromophenol is formed as white precipitate.
What is product obtained when phenol reacts with bromine water bromine and CS2?
When phenol is treated with excess bromine water it gives a M bromophenol B O and p bromophenol?
Therefore, the answer is – option (d) – When phenol is treated with excess bromine water, it gives 2,4,6-tribromophenol.
Which of the following is major product when phenol reacts with Br2 solution that is prepared in CS2 at low temperature?
p-bromophenol
Phenol reacts with bromine in CS2 at low temperature to give o and p-bromophenol. Was this answer helpful?
What are the main products when phenol reacts with Br2 in aqueous solution and in carbon disulphide?
Which is the product when phenol reacts with `Br_(2)` in presence of `CS_2` at 278 K temp.? Assertion : Phenol forms 2, 4, 6-tribromophenol on treatment with Br2 in carbon disulphide at 273 K. Reason : Bromine polarises in carbon disulphide.
When phenol reacts with bromine in CS _( 2 at a low temperature the product is?
Phenol reacts with bromine in CS2 at low temperature to give o and p-bromophenol.
When phenol is treated with excess bromine water it gives M bromophenol O and p Bromophenols 2 4 Dibromophenol 2,4,6-tribromophenol?
Which of the following gives precipitate with excess bromine water?
Phenol
Phenol, when treated with the excess of bromine water, gives a white precipitate of 2,4,6 -tribromophenol as shown in the reaction. Was this answer helpful?
Which of the following is the major product formed when phenol is treated with Br2 in CS2 at 273 K?
The products formed in the reaction of phenol with Br2 dissolved in CS2 at 0oC are o-bromophenol and p-bromophenol.
What is the major product of bromination of phenol?
Phenol has activating (electron releasing) −OH group and bromine water supplies Br+ ion easily, hence under such conditions reaction does not stop at monobromo or dibromo stage but a fully brominated (2,4,6,-tribromophenol) compound is the final product.
What happens when phenol reacts with bromine in presence of water and carbon di sulphide separately?
Explanation: When phenol is reacted with bromine in the presence of a non-polar compound which is (carbon disulfide), it results in the formation of two products. The products are ortho-bormophenol and para-bromophenol.
What gas is produced when phenols react with bromine water?
Reaction with bromine water If 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. The precipitate is 2,4,6-tribromophenol.
What will be the product’s formed when phenol reacts with bromine at low temperature?
Phenol reacts with bromine in CS2 at low temperature to give o and p-bromophenol.
What happens when phenol react with br2 solution?
When phenol reacts with bromine water 2,4,6- tribromophenol is formed. Bromine water is decolourises and a white precipitate is formed.
Does phenol react with bromine?
For example, as you will find below, phenol will react with a solution of bromine in water (bromine water) in the cold and in the absence of any catalyst. It also reacts with dilute nitric acid, whereas benzene itself needs a nitrating mixture of concentrated nitric acid and concentrated sulphuric acid.
What is bromination of phenol?
Bromination of phenol is a substitution reaction. Where the bromine replaces hydrogen present in the benzene ring of phenol. In the water solvent when phenol treated with Br2. gives a polybromo derivative in which all hydrogen atoms at ortho, meta, and para positions with respect to the −OH.
