Question

Assertion (A): Simple distillation can help in separating a mixture of propan-1-ol (Boiling point ${97}^{\circ }$) and propanone (boiling point ${56}^{\circ }$).

Reason (R): Liquids with a difference of more than ${20}^{\circ }$ in their boiling points can be separated by simple distillation.

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

Answer 1

The correct option is B

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

Analyzing the assertion and reason

Simple distillation method is used to separate

$\left(i\right)$ Volatile liquids from non-volatile impurities and

$\left(ii\right)$ The liquids having sufficient difference in their boiling points (More than ${20}^{\circ }$).

Since, the boiling point difference of propan-1-ol and propanone is greater than ${20}^{\circ }C$. So, a simple distillation technique can be used to separate them.

Hence, Both assertion and reason are correct and reason is the correct explanation of assertion.

So, option (A) is the correct answer.
