A chemical process or reaction in which a halogen element is introduced into a substance.
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.
free-radical halogenation of acetic acid
Halogenation is the result that occurs when a chemical is mixed with a halogen.
Halogenation is typically carried out in an anti fashion.
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.
because we need hydrogen as well as chlorine in that reaction
alkenes are neutral nucleofiles they undergoes electrophilic addition reactions.
An alkene can undergo halogenation when combined with chlorine or bromine in a halogenation reaction to form a dihalogenated alkane. This reaction involves the addition of a halogen atom across the double bond of the alkene.
because halogenation of alkanes with fluorine is very violently exothermic i.e explosive in nature .
In acidic conditions, alpha halogenation involves the substitution of a hydrogen atom with a halogen atom at the alpha position of a carbonyl compound. This reaction is typically catalyzed by an acid, such as hydrochloric acid, and proceeds through the formation of an enol intermediate, which is then attacked by the halogen to form the halogenated product.
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.
