tertiary alcohol by $S_N1$

Vedclass · Answer

(B) The reaction of an alcohol with Lucas reagent $(conc. \ HCl + ZnCl_2)$ proceeds via an $S_N1$ mechanism.In this reaction,the rate-determining step is the formation of a carbocation intermediate.The stability of the carbocation follows the order: $3^{\circ} > 2^{\circ} > 1^{\circ}$.Since a tertiary $(3^{\circ})$ alcohol forms the most stable carbocation,it reacts the fastest with the Lucas reagent.

An unknown alcohol is treated with the "Lucas reagent" to determine whether the alcohol is primary,secondary,or tertiary. Which alcohol reacts fastest and by what mechanism?
