Solution
Correct Answer:
25 K
Simple Distillation allows for the separation of a volatile liquid from non-volatile impurities or from another liquid with a significantly different boiling point.
- Boiling Point Difference: For effective separation using simple distillation, the components of the mixture must have a boiling point difference of at least 25 K (or 25∘C).
- If the boiling points are closer than this, the vapors produced will be a mixture of both components, and Fractional Distillation (using a fractionating column) must be employed to achieve purity.
This easy difficulty chemistry question is from the chapter purification and characterisation of organic compounds, covering the topic of distillation. It appeared in the 2025 exam.
