Simple distillation technique is used for separating components that have a difference of more than 20∘C in their boiling points. Thus, the statement 'simple distillation can help in separating a mixture of propan-1-ol (boiling point 97∘C) and propanone (boiling point 56∘C)' is correct. Thus, the assertion is correct.

Assertion (A): Simple distillation can help in separating a mixture of propan-1-ol (boiling point 97°C) and propanone (boiling point 56°C).
Reason (R): Liquids with a difference of more than 20°C in their boiling points can be separated by simple distillation.
Explanation:
Simple distillation is a commonly used method for separating two or more liquids with significantly different boiling points. It relies on the principle that when a mixture of liquids is heated, the liquid with the lower boiling point vaporizes first, while the one with the higher boiling point remains as a liquid. The vapor is then condensed and collected, resulting in the separation of the components.
In the given scenario, propan-1-ol and propanone have boiling points of 97°C and 56°C, respectively. The difference in their boiling points is 41°C, which is more than the suggested 20°C difference stated in the reason.
Therefore, both the assertion and the reason are correct. The reason provides a valid explanation for why simple distillation can be used to separate the mixture of propan-1-ol and propanone.
Key Points:
- Simple distillation is a method used to separate liquids with different boiling points.
- It relies on heating the mixture and collecting the vapor of the lower boiling point component.
- Liquids with a difference of more than 20°C in their boiling points can be effectively separated by simple distillation.
- In the given scenario, the mixture of propan-1-ol and propanone can be separated using simple distillation because their boiling points have a difference of 41°C.
Conclusion:
Both the assertion and the reason are correct, and the reason provides a valid explanation for the assertion.
