Question
Match items of column I and II Match List I with List II List I List II A. H2O/CH2Cl2 I. Crystallization B. II. Differential solvent extraction C. Kerosene/Naphthalene III. Column chromatography D. C6H12O6/NaCl IV. Fractional Distillation (A) A-(iii), B-(iv), C-(ii), D-(i) (B) A-(i), B-(iii), C-(ii), D-(iv) (C) A-(ii), B-(iv), C-(i), D-(iii) (D) A-(ii), B-(iii), C-(iv), D-(i)
💡 Solution & Explanation
(A) CH2Cl2 and H2O do not mix & form two separate layer so they can be separated by Differential solvent extraction. (B) Column chromatography. (C) Fractional Distillation, kerosene and naphthalene are different types of hydrocarbons that have different boiling points. (D) Crystallization, C6H12O6 and NaCl are different compounds with different chemical and physical properties. As a result they can be separated from each other by crystallization.
