Vedclass · Answer

(A) Lucas test is used to distinguish between primary,secondary,and tertiary alcohols.Lucas reagent is a mixture of concentrated $HCl$ and anhydrous $ZnCl_2$.The reaction proceeds via an $SN^1$ mechanism,where a carbocation is formed as an intermediate.The rate of the reaction depends on the stability of the carbocation formed.The stability order of carbocations is tertiary $>$ secondary $>$ primary.Therefore,the reactivity order of alcohols with Lucas reagent is tertiary $>$ secondary $>$ primary.$(CH_3)_3COH$ is a tertiary alcohol,so it reacts most readily with the Lucas reagent.
