The process of halogenation is a chemical reaction between a compound, usually an organic compound and a halogen. An example of halogenation is fluorination or chlorination.
Halogenation is the result that occurs when a chemical is mixed with a halogen.
Halogenation
Well, darling, the reason direct halogenation of aniline is a big no-no is because aniline is a strong activating group that will make the halogenation reaction go haywire and give you a messy mixture of products. Plus, the lone pair on the nitrogen atom in aniline will coordinate with the halogenating agent, making it more selective towards other positions on the ring. So, in a nutshell, direct halogenation of aniline is a recipe for disaster in the lab.
Aromatic compounds undergo halogenation primarily due to the presence of the delocalized π-electron system in their benzene rings, which can stabilize the formation of an intermediate sigma complex. The reaction typically requires a catalyst, such as iron (III) bromide or aluminum chloride, to facilitate the electrophilic substitution process. During halogenation, a halogen molecule is activated to form a more reactive electrophile, allowing it to substitute one of the hydrogen atoms on the aromatic ring without disrupting the overall aromatic stability. This process preserves the aromatic character of the compound while introducing halogen functional groups.
When Iodine solid reacts with this alkene in presence of ethanol 1,2-diiodo-3-ethyl penman is produced stereo chemistry of produced compound shows a significant role for determining the properties of product.
An enzyme has the role of a catalyst but in biochemistry.
