Question

Which reagent cannot be used to prepare an alkyl halide from an alcohol ? (A)  HCl + ZnCl2 (B) NaCl (C) PCl5 (D)  SOCl2

Tardigrade Admin · Accepted Answer

NaCl is an ionic compound cannot displace - OH by Cl. Rest all other reagents ( HCl + ZnCl2 , PCl5,SOCl2 ) displaces -OH from alcohol and provide Cl- as a nucleophile.

Q. Which reagent cannot be used to prepare an alkyl halide from an alcohol ?

$H Cl + Z n C l_{2}$

$N a Cl$

$PC l_{5}$

$SOC l_{2}$

$N a Cl$ is an ionic compound cannot displace $- O H$ by $Cl$ . Rest all other reagents $(H Cl + Z n C l_{2}, PC l_{5}, SOC l_{2})$ displaces $- O H$ from alcohol and provide $C l^{-}$ as a nucleophile.
