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 !!
