Simple distillation is a procedure by which two liquids with different boiling points can be separated. Simple distillation (the procedure outlined below) can be used effectively to separate liquids that have at least 20℃ difference in their boiling points.
Thus, a mixture of propan-1-ol and propanone can be separated by simple distillation.
Hence, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
