How will you convert phenol to 2 4 6 Tri nitrophenol?
When concentrated nitric acid is added to phenol in the presence of sulphuric acid it gives 2, 4, 6-trinitrophenol.
How is phenol converted into benzoquinone?
Phenol is convert into benzoquinone by carrying its oxidation with sodium dichromate in the presence of conc.H2SO4.
Why Tribromophenol is formed?
The action of bromine on phenol can be explained as. Phenol reacts with bromine water to give 2,4,6-tribromophenol. … Phenol reacts with bromine in a presence of Carbon disulphide to form a mixture of o-bromophenol and p-bromophenol.
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.
How is phenol benzene prepared?
To make Benzene from Phenol, Phenol reacts with Zinc dust at a higher temperature, the phenol, is converted to a phenoxide ion and a proton, which accepts an electron from Zn forming an H radical. Which results in the formation of ZnO and the phenoxide ion that was formed, converts itself into Benzene.
What is Tribromophenol used for?
2,4,6-Tribromophenol (TBP) is a brominated derivative of phenol. It is used as a fungicide, as a wood preservative, and an intermediate in the preparation of flame retardants. Any minor or unwanted substance introduced into the environment that can have undesired effects.

What amount of bromine will be required to convert?
10.22 grams of bromine will be required to convert 2 gm of phenol into 2, 4, 6 -tribromophenol. Therefore, 2g of phenol requires = (480/94)×2 = 10.22 g.
What is nitration of phenol?
Nitration of Phenols. When phenol is treated with concentrated nitric acid, the nitration results in the formation of 2, 4, 6-trinitrophenol (commonly called picric acid). Formation of 2, 4, 6-trinitrophenol.
Why is phenol more reactive than benzene?
The increased reactivity compared to benzene is due to the lone pair of p-orbital electrons on the oxygen atom in the phenol group. The electron pair is delocalised into the ring structure, activating the ring. This increases the electron density of the molecule, which induces dipoles in the bromine molecule.
What happens when phenol is treated 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.

How do you make ethane from ethene?
Ethane when reacted with Chlorine (halogenation) in presence of sunlight gives ethyl chloride. Now, Ethyl chloride on reaction with KOH (Alcoholic) gives ethene.
How is benzoquinone made?
1,4-Benzoquinone is prepared industrially by oxidation of hydroquinone, which can be obtained by several routes. … Another major process involves the direct hydroxylation of phenol by acidic hydrogen peroxide: C6H5OH + H2O2 → C6H4(OH)2 + H2O Both hydroquinone and catechol are produced.
How do you convert aniline to phenol?
Thus, we can convert aniline to phenol by first treating aniline with sodium nitride and hydrochloric acid which gives benzene diazonium salt which in reaction with water gives phenol. Note: In the reaction, phenol is prepared. Thus, it is a preparation reaction of phenol.
