Vedclass · Answer

(D) Primary,secondary,and tertiary alcohols can be distinguished using the oxidation method,Lucas test,and Victor-Meyer's method.$1.$ Oxidation method: Primary alcohols oxidize to aldehydes and then to carboxylic acids. Secondary alcohols oxidize to ketones and resist further oxidation. Tertiary alcohols are generally resistant to oxidation under these conditions.$2.$ Lucas test: This test uses Lucas reagent (conc. $HCl$ and anhydrous $ZnCl_2$). Tertiary alcohols react immediately to form turbidity,secondary alcohols react within $5-10$ minutes,and primary alcohols show no reaction at room temperature.$3.$ Victor-Meyer's method: Alcohols are converted to nitroalkanes and treated with nitrous acid and alkali. Primary alcohols yield a blood-red color,secondary alcohols yield a blue color,and tertiary alcohols remain colorless.
