Why is thionyl chloride (SOClX2) preferred for preparing alkyl chlorides from alcohols, as opposed to say PClX5 or PClX3 ?
Answer
Thionyl chloride is preferred for preparing alkyl chlorides from alcohols because the by-products formed in the reaction are SOX2 and HCl which are in gaseous form and escape into the atmosphere leaving behind pure alkyl chlorides.
CHX3CHX2−OH+SOClX2⟶CHX3CHX2−Cl+SOX2↑+HCl↑
