The best method for the conversion of an alcohol into an alkyl chloride is by treating the alcohol with

Answer»

`PCl_(5)`
`SOCl_(2)` in presence of pyridine
Dry HCl in the presence of anhydrous `ZnCl_(2)`
`PCl_(3)`

Solution :`R-OH+SOCl_(2) UNDERSET("Reflux")overset("Pyridine")(to)R-Cl+SO_(2)uarr+HCluarr`
This is the best method for preparing alkyl chloride from alcohols. The advantage of this method over USING phosphorus chlorides is that the byproducts of the above reaction i.e. `SO_(2)` and HCl are gases which can EASILY escape from the reaction MIXTURE.
