Vedclass · Answer

(B) The reaction of alcohols with Lucas reagent $(conc. HCl + anhydrous ZnCl_2)$ is known as the Lucas test. This test is used to distinguish between primary,secondary,and tertiary alcohols. - Tertiary $(3^o)$ alcohols react immediately to form an alkyl chloride,which appears as turbidity in the solution. - Secondary $(2^o)$ alcohols show turbidity within $5-10$ minutes. - Primary $(1^o)$ alcohols do not show turbidity at room temperature. Analyzing the options: - Option $A$ is a secondary alcohol. - Option $B$ is a tertiary alcohol (the $-OH$ group is attached to a carbon atom that is bonded to three other carbon atoms). - Option $C$ is a primary alcohol. - Option $D$ is a secondary alcohol. Therefore,the tertiary alcohol in option $B$ will show turbidity immediately.
