What product form when anisole react with HI?
Phenol, though additional iodide salt is sometimes needed.
Anisole does not form peroxide easily why?
Anisole has a low reactivity towards peroxide formation due to its relatively low susceptibility to autoxidation. This is because the aromatic ring stabilizes the intermediate radicals that are necessary for peroxide formation. Additionally, anisole does not contain any easily abstractable hydrogens that are required for peroxide formation.
Why phenol is more reactive than anisol?
Phenol is more reactive than anisole because the hydroxyl group in phenol is a stronger activating group compared to the methoxy group in anisole. The resonance stabilization of the phenoxide ion formed during reactions further enhances its reactivity. In contrast, anisole's methoxy group is a weaker activating group and does not stabilize the negative charge as effectively.
Why is anisole ortho and para director towards electrophile substitution reaction?
Anisole is ortho and para directing in electrophilic aromatic substitution reactions because the lone pairs on the oxygen atom can donate electron density to the ring through resonance, stabilizing the carbocation intermediate formed during the reaction at the ortho and para positions. This makes those positions more favorable for electrophilic attack.
Why does the friedel crafts acylation of anisole favor the para-methoxyacetophenone?
Anisole has a methoxyl group that participates in activating the benzene ring during acylation. When the benzene ring breaks its bond in order to attach an acetone functional group, it is destablized and therefore energy unfavorable. However, other functional groups like alkoxides (-OR) animo (-NR2), thio groups (-SR) all have lone electrons AND single bonds, which can form into double bonds--donating those electrons to the benzene ring and stabilizing its positive charge. The attachment will always para to the activating group due to steric effects, followed by ortho position due to specific locations that the positive charge can exist (when the methoxyl group adds its electrons).
What is the atomic number for Anisole?
Anisole is a compound, not an element and so it does not have an atomic number. It is composed of carbon, hydrogen, and oxygen which have the atomic numbers 6,1, and 8 respectively.
Why doesn't Anisole form peroxide easily?
Anisole is less likely to form peroxides compared to other ethers because the aromatic ring in anisole stabilizes the molecule through resonance. This stability makes it less susceptible to undergoing reactions that lead to peroxide formation. Additionally, anisole tends to have fewer labile hydrogen atoms that can participate in peroxide formation reactions.
What is an anisole?
An anisole is a type of aromatic compound that has a methoxy group (-OCH3) attached to a benzene ring. It is often used as a solvent in various chemical reactions and as a starting material for the synthesis of other compounds. Anisole has a sweet, pleasant odor and is a colorless liquid at room temperature.

Give a simple procedure to convert anisole into phenol?
Anisole can be converted into phenol by using a strong aqueous acid, such as hydrochloric acid, in the presence of water and heat. The acidic conditions will cleave the methoxy group (–OCH3) from the benzene ring, resulting in the formation of phenol. This reaction is known as hydrolysis of an ether.
What is an anisyl?
An anisyl is any of three isomeric univalent radicals derived from anisole.
How anisole is prepared from phenol?
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.
Why is anisole ortho and para director towards electrophile substitution reaction?
Anisole is ortho and para directing in electrophilic aromatic substitution reactions because the lone pairs on the oxygen atom can donate electron density to the ring through resonance, stabilizing the carbocation intermediate formed during the reaction at the ortho and para positions.

What is anasoles use?
Anisole is mainly used for its derivatives for many natural and artificial toiletry uses. Its derivatives are often used in items like perfume, pharmaceuticals, and some insect pheromones.
