explain the halogenation of anisole
Answers
Answer:
Anisole undergo bromination with bromine in ethanoic acid (acetic acid) to form mixture of ortho and para bromo anisole. It is an example of electrophilic aromatic substitution reaction. H atom attached to benzene ring is replaced with bromine atom. Methoxy group is ortho para directing group.

Answer:
Halogenation is electrophilic. An electrophilic aromatic halogenation is a form of electrophilic aromatic substitution in organic chemistry.
Explanation:
Anisole is subjected to halogenation in the presence of a catalyst CH₃COOH (acetic acid). It results in the formation of an ortho product as well as a para product,
A substance or product can be halogenated by a chemical process in which one or more halogens are added.
The structural features and functional groups of the organic substrate, as well as the actual halogen, affect the halogenation process and stoichiometry.
Inorganic substances can also be halogenated, unlike metals.
RC₆H₅ + X₂ → HX + RC₆H₄X is an electrophilic halogenation of aromatic compounds. Only chlorine and bromine may be used in this reaction, which is carried out in the presence of a Lewis acid like FeX₃ (laboratory method).
The function of the Lewis acid is to polarise the halogen-halogen bond, increasing the electrophilicity of the halogen molecule. In the industrial setting, this is accomplished by treating the aromatic chemical with X₂ in the presence of iron metal.
The iron interacts with the halogen as it is fed into the vessel reaction, creating catalytic concentrations of FeX₃. The following might be the reaction's mechanism: The above method would not work since fluorine is very reactive, and the aromatic molecule would react negatively with F₂.
The halogenation of anisole is explained above.
