Vedclass · Answer

(D) Lucas reagent is a mixture of concentrated $HCl$ and anhydrous $ZnCl_2$. The reaction of alcohols with Lucas reagent proceeds via an $S_N1$ mechanism,which involves the formation of a carbocation intermediate. The reactivity of alcohols towards Lucas reagent follows the order: $3^{\circ} > 2^{\circ} > 1^{\circ}$.$(A)$ $CH_3-CH_2-CH_2-CH_2-OH$ is a $1^{\circ}$ alcohol.$(B)$ $CH_3-CH_2-CH(OH)-CH_3$ is a $2^{\circ}$ alcohol.$(C)$ $(CH_3)_2CH-CH_2-OH$ is a $1^{\circ}$ alcohol.$(D)$ $(CH_3)_3C-OH$ is a $3^{\circ}$ alcohol.Since $3^{\circ}$ alcohols form the most stable carbocation,they react fastest with Lucas reagent,often at room temperature.
