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.

Options

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

Explanation

To solve the assertion and reason question, we will follow these steps:

### Step 1: Understand the Assertion
The assertion states that simple distillation can help in separating a mixture of propan-1-ol (boiling point 97°C) and propanone (boiling point 56°C).

### Step 2: Understand the Reason
The reason provided states that liquids with a difference of more than 20°C in their boiling points can be separated by simple distillation.

### Step 3: Calculate the Difference in Boiling Points
To determine if the assertion is valid, we need to calculate the difference in boiling points between propan-1-ol and propanone.

- Boiling point of propan-1-ol = 97°C
- Boiling point of propanone = 56°C

Difference = 97°C - 56°C = 41°C

### Step 4: Analyze the Difference
Since the difference in boiling points (41°C) is greater than 20°C, it confirms that simple distillation can indeed be used to separate these two liquids.

### Step 5: Conclusion
Both the assertion and the reason are correct. The reason correctly explains why the assertion is true, as the difference in boiling points is sufficient for separation by simple distillation.

### Final Answer
Both assertion (A) and reason (R) are correct, and reason (R) is the correct explanation of assertion (A).
