Strategy:\n> Match common lab purification methods to appropriate mixtures based on physical properties like boiling point difference and miscibility.\n\n- (A) Simple distillation: Chloroform (61°C) + Aniline (184°C) large . (III)\n- (B) Fractional distillation: Diesel + Petrol crude oil fractions. (I)\n- (C) Reduced pressure (Vacuum): Glycerol (bp 290°C, decomposes). (IV)\n- (D) Steam distillation: Aniline (volatile with steam, water-immiscible). (II)\n\n
