Vedclass · Answer

(D) The Lucas test uses conc. $HCl$ and anhydrous $ZnCl_2$ to distinguish between primary,secondary,and tertiary alcohols. Tertiary alcohols react instantly to produce turbidity due to the formation of an insoluble alkyl chloride. Given the molecular formula $C_5H_{12}O$,the alcohol $X$ must be a tertiary alcohol,which is $2-$methyl$-2-$butanol. Acid-catalysed hydration of $2-$methyl$-1-$butene follows Markovnikov's rule to yield $2-$methyl$-2-$butanol,which is a tertiary alcohol. Therefore,option $D$ is the correct answer.

An alcohol $X$ $(C_5H_{12}O)$ when reacted with conc. $HCl$ and anhydrous $ZnCl_2$ produces turbidity instantly. The alcohol $X$ can be prepared from which of the following reactions?
