Vedclass · Answer

(B) The preparation of alkyl chlorides from alcohols involves the substitution of the $-OH$ group with a $Cl$ atom. $1$. $HCl +$ Anhydrous $ZnCl_2$ (Lucas reagent) is used to convert alcohols to alkyl chlorides. $2$. $PCl_5$ reacts with alcohols to form alkyl chlorides $(R-OH + PCl_5 \rightarrow R-Cl + POCl_3 + HCl)$. $3$. $SOCl_2$ (Thionyl chloride) is the preferred reagent for preparing alkyl chlorides because the by-products ($SO_2$ and $HCl$) are gases,leaving the pure alkyl chloride. $4$. $NaCl$ is an ionic compound and cannot directly substitute the $-OH$ group of an alcohol to form an alkyl chloride under standard conditions,as the $Cl^-$ ion is a poor nucleophile in this context and the $-OH$ group is a poor leaving group. Therefore,$NaCl$ is not useful for this transformation.

Which of the following reagents is $NOT$ useful for the preparation of alkyl chloride from alcohol?
