Vedclass · Answer

(D) The reaction of alcohols with Lucas reagent $(conc. HCl + 	ext{anhydrous } ZnCl_2)$ is used to distinguish between $1^\circ, 2^\circ,$ and $3^\circ$ alcohols.The reaction follows an $S_N1$ mechanism,and the rate depends on the stability of the carbocation formed.Tertiary $(3^\circ)$ alcohols form stable $3^\circ$ carbocations and thus react immediately to form insoluble alkyl chlorides,which appear as turbidity.Among the given options,$2$-methyl$-2-$butanol is a $3^\circ$ alcohol,so it gives immediate turbidity.

Which of the following gives immediate turbidity on reaction with Lucas reagent $(HCl/ZnCl_2)$?
