Vedclass · Answer

(D) The mixture of conc. $HCl$ and anhydrous $ZnCl_2$ is known as Lucas reagent.This reaction proceeds via the formation of a carbocation intermediate.The reactivity order of alcohols towards Lucas reagent is $3^o > 2^o > 1^o$.$2$-methylbutan-$2$-ol is a tertiary $(3^o)$ alcohol,while the others are primary or secondary alcohols.Therefore,$2$-methylbutan-$2$-ol reacts fastest with Lucas reagent,producing immediate turbidity.

Amongst the following alcohols,which would react fastest with conc. $HCl$ and $ZnCl_2$?
