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
2-nitro toluene may under go electrophilic substitution reactions as Nitration, Halogenation at 4th position.
Bromine is less reactive than chlorine (and much less so than fluorine) so it is selective when it comes to halogenation substitution reactions.
Carbonyl compounds can be halogenated through either base or acid catalysis, although a difference in products can be expected; acid catalysis is more likely to produce alpha-monohalogenated carbonyl compounds (although polyhalogenation is also possible with acid), and base is more likely to produce a polyhalogenated alpha carbonyl compound. Halogenation occurs through an enolate/enol intermediate (base or acid respectively). In the case of basic halogenation an enolate is formed at the alpha position of the carbonyl carbon. The enolate (nucleohile) then attacks the halogen (Br2, Cl2, I2-typically not F2) since the halogen molecule acts as a polarized electrophile. The monohalogenated product is now more reactive than the unhalogenated reactant since the electron withdrawing halogen makes any alpha protons remaining even more acidic and susceptible to abstraction via base to create another enolate, and the process can be repeated.

Halogenation
Electrophilic halogenation
Electrophilic halogenation
A chemical process or reaction in which a halogen element is introduced into a substance.
because we need hydrogen as well as chlorine in that reaction
alkenes are neutral nucleofiles they undergoes electrophilic addition reactions.
because halogenation of alkanes with fluorine is very violently exothermic i.e explosive in nature .

The HVZ Reaction is an organic reaction and stands for the Hell-Volhard-Zelinsky halogenation reaction. It involves replacing an alpha-hydrogen with a halogen.
LDA stands for lithium diisopropylamide. This compound causes a number of reactions, including the alkylation and halogenation of enolates, and the Aldol reaction.
