Haloalkanes can be prepared using various methods, primarily involving substitution or addition reactions.

• From Alcohols: Haloalkanes are obtained by reacting alcohols with halogen acids (HX), phosphorus halides, or thionyl chloride
• From Alkanes: Free radical halogenation of alkanes with Cl₂ or Br₂ in the presence of UV light produces haloalkanes, though it gives a mixture of products.
