because, phenol it self neucleophilic group.
Reactivity in general between the two is quite difficult to compare since the aromatic ring of phenol is able to undergo reactions which ethanol isn't and vice versa. However, there are a number of reactions which can be compared. The first of these is deprotonation, affecting the acidity of the alcohol. Since the subsequent negative charge on the oxygen is stabilised over the benzene ring, phenol is significantly more acid than ethanol (about 100,000 times). Nuclephilic substitution with the alcohol as the nucleophile is likely to be slightly quicker using phenol due to this easier deprotonation creating a stronger nucleophile than the ethanol. Another common reaction is nucleophilic substitution with the alcohol as the electrophile, which occurs fairly easily to ethanol in the presence of an acid. Phenol however, due to its ring, cannot easily react in the same way.
The phenoxide ion is more reactive than phenol towards electrophilic substitution reactions because the phenoxide ion is a stronger nucleophile due to the negative charge on oxygen. This makes it more effective in attacking electrophiles in substitution reactions. Additionally, the negative charge on the phenoxide ion stabilizes the transition state, lowering the activation energy for the reaction to occur.
Phenol is generally more reactive than aniline in electrophilic substitution reactions. This is because the hydroxyl group in phenol strongly activates the aromatic ring towards electrophiles, enhancing reactivity. In contrast, the amino group in aniline also activates the ring but can be deactivated by factors such as steric hindrance and the basicity of the nitrogen. Therefore, while both are reactive, phenol typically shows greater reactivity in these contexts.
Phenol gets darkened on long standing due to oxidation reactions that form quinones and polymers. These reactions are accelerated by exposure to light and air. The darkening of phenol is a result of the formation of colored compounds as a byproduct of these oxidation reactions.
Anisole can be prepared from phenol through a process called methylation. In this reaction, phenol is treated with methyl iodide (or another methylating agent) in the presence of a base, such as sodium hydroxide or potassium carbonate, to facilitate the substitution of a hydrogen atom on the phenolic hydroxyl group with a methyl group. The resulting product is anisole, or methoxybenzene. This reaction typically occurs via an SN2 mechanism, where the base deprotonates the phenol, allowing for nucleophilic attack on the methyl iodide.
Chlorobenzene can undergo various reactions, including substitution, nitration, and halogenation. It can also be converted to phenol through hydrolysis. Additionally, chlorobenzene can participate in electrophilic aromatic substitution reactions.
The substitution reactions of phenol are easier than benzene, phenol directly reacts with bromine and gives tribromo phenol while benzene requires FeCl3 as a catalyst and gives mono bromo phenol.
In the presence of aqueous NaOH, phenol undergoes nucleophilic aromatic substitution reaction to form sodium phenoxide. When CCl4 is added, no reaction occurs as CCl4 is non-reactive towards phenoxide ion.
Phenol is nitrated faster than toluene because phenol is more reactive towards electrophilic aromatic substitution reactions due to the presence of the hydroxyl group (-OH) which activates the benzene ring by donating electrons to it. This increases the electron density on the ring and makes it more susceptible to electrophilic attack by the nitronium ion in nitration reactions.
Phenol and benzene are both aromatic compounds, but phenol has a hydroxyl group (-OH) attached to the benzene ring, making it more reactive than benzene. Phenol can undergo reactions such as oxidation and substitution more readily than benzene. Additionally, phenol is more acidic than benzene due to the presence of the hydroxyl group.
When bromine reacts with phenol, it undergoes electrophilic aromatic substitution to brominate the aromatic ring. The reaction takes place under mild conditions without a catalyst, and the product formed is a bromophenol compound.
you can say as it contain Phenol ring that is undergoes acetylation process to form -OCOCH3

The reaction between phenol and bromine water results in the substitution of a hydrogen atom on the benzene ring with a bromine atom. This forms bromophenol as the product. The reaction is a bromination reaction and the presence of phenol's hydroxyl group activates the benzene ring towards electrophilic substitution.
