To solve this problem, we need to understand the reaction of alcohols with Lucas reagent.$\newline$Lucas reagent is a mixture of concentrated hydrochloric acid and zinc chloride (ZnCl$_2$).$\newline$The reaction rate with Lucas reagent depends on the type of alcohol:$\newline$• Tertiary alcohols react almost instantaneously.$\newline$• Secondary alcohols react within a few minutes.$\newline$• Primary alcohols take a long time to react.$\newline$Let's analyze the given options:$\newline$Option 1: $$(CH$_3$)CH-CH$_2$OH$$ is a secondary alcohol.$\newline$Option 2: $$(CH$_3$)C(OH)(CH$_3$)$$ is a tertiary alcohol.$\newline$Option 3: $$CH$_3$-CH$_2$-CH$_2$-CH$_2$OH$$ is a primary alcohol.$\newline$Option 4: $$CH$_3$-CH$_2$-CH(OH)-CH$_3$ is a secondary alcohol.$\newline$Since tertiary alcohols react instantaneously with Lucas reagent, the correct answer is Option 2.
