प्रश्न

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.

पर्याय

  • Both A and R are correct and R is the correct explanation of A.

  • Both A and R are correct but R is not the correct explanation of A.

  • Both A and R are not correct.

  • A is not correct but R is correct.

MCQ

उत्तर

Both A and R are correct and R is the correct explanation of A.

Explanation:

Since the liquids are having sufficient difference in their boiling points. Liquids having different boiling points vaporize at different temperatures. The vapours are cooled, and the liquids so formed are collected separately.
