Which of the following binary mixtures is best separated by simple distillation? — Practical Organic Chemistry and Purification Chemistry Question

💡 Solution & Explanation

Chloroform (b.p. $334\text{ K}$) and aniline (b.p. $457\text{ K}$) have a large boiling point difference ($> 20\text{ K}$ or $80^\circ\text{C}$) and are easily separated by simple distillation.
