Phenols do not react with HX (hydrogen halides) because the oxygen atom in the phenol molecule is more electronegative than the hydrogen atom attached to the halogen in HX. This leads to stabilization of the phenol ring structure through resonance, making it less favorable for the hydrogen halide to protonate the phenol.

What is formed when phenol reacts with amonium sulphite in presence of ammonia?
When phenol reacts with ammonium sulfite in the presence of ammonia, the result is the formation of a salt called ammonium phenoxide. This reaction involves the replacement of the hydrogen in the phenol with the ammonium cation from the ammonium sulfite.
What is the result of iodoform reacting with phenol?
When iodoform reacts with phenol, the iodoform is reduced to triiodomethane and phenol is oxidized to benzoquinone. The reaction results in the formation of a white precipitate of triiodomethane.
Phenol when it first reacts with conc sulfuric acid and then with conc nitric acid gives?
Phenol reacts with concentrated sulfuric acid to form the sulfonated product, and then with concentrated nitric acid to form picric acid (2,4,6-trinitrophenol).
Is phenol soluble in sodium hydroxide?
Yes, phenol is soluble in sodium hydroxide due to the formation of the water-soluble sodium phenolate salt. Phenol reacts with sodium hydroxide to form sodium phenolate and water.
What happens when phenol reacts with concentrated HNO3 plus H2SO4?
When phenol reacts with concentrated nitric acid (HNO3) in the presence of sulfuric acid (H2SO4), a mixture of products is formed, including picric acid (2,4,6-trinitrophenol) and water. This reaction is known as nitration of phenol and is used to synthesize picric acid, which is a yellow, explosive compound.
Does phenol react with bromine?
Yes, at room temperature bromine reacts with phenol and forms 2,4,6-tribromo phenol.

What is formed when phenol reacts with Hinsberg reagent?
Hinsberg reagent is used for amines.

What is the reaction of phenol with phosphorus pentachloride?
There is no reaction when their molar ratio is around 1...but when phenol is present in excess it gives triphenylphosphate....

What product form when anisole react with HI?
Phenol, though additional iodide salt is sometimes needed.
What happens to glucose in the phenol sulfuric acid test?
In the phenol sulfuric acid test, glucose reacts with phenol and sulfuric acid to form a colored product. The color change is due to the formation of furfural, which reacts with the sulfuric acid to produce a colored compound. This color change is used to detect the presence of glucose in a sample.
What type of reaction between phenol and potassium permanganate?
Phenol reacts with potassium permanganate in an acidic medium to form benzoquinone as the main product, along with small amounts of hydroquinone. This reaction is a redox reaction where phenol is oxidized to form benzoquinone.
