while almost haloalkanes are human produced..

general method is when alkanes react with free radical halogenation...in this rxn H atom is removed from alkane,,then replaced by a halogen atom by reaction with a diatomic halogen molecule.

Dear akansha sawhney,

The General Method by which you prepare a Haloalkane is from an Alcohol !!

Alcohols on tratment with Sulphonyl Chloride[SOCl2](most preferrable) gives haloalkanes !

CH3CH2OH + SOCl2 ---------->  CH3CH2Cl + SO2 + HCl

The Separation of the Haloalkane & Hydrogen chloride & Sulpher di-oxide are easier because SOCl2 & HCl are volaitle !!

Thus this is the generally eaier way to prepare Haloalkanes !!

 

All the Best & Good Luck!!

Sorry to say that,SOCl2 is not most preferred reagent.Oxalyl chloride is the best reagent.
