In the following question, a statement of assertion is followed by a statement of reason. Mark the correct choice.
Assertion: Simple distillation can help in separating a mixture of propan-1-ol (boiling point `97^(@)C`) and propanone (boiling point `56^(@)C`)
Reason: Liquids with a difference of more than `20^(@)C` in their boiling points can be separated by simple distillation.

Options

A. both assertion and reason are true and reason is the correct explanationn of assertion
B. both assertionn and reason are true but reason is not the correct explanation of assertion
C. Assertionis true but reason is false.
D. both assertion and reason are false.

Answer

To solve the given question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding 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).
- We need to check if this statement is true.

2. **Boiling Point Difference**:
- Calculate the difference in boiling points:
- Boiling point of propan-1-ol = 97°C
- Boiling point of propanone = 56°C
- Difference = 97°C - 56°C = 41°C
- Since 41°C is greater than 20°C, the assertion is true.

3. **Understanding the Reason**:
- The reason states that liquids with a difference of more than 20°C in their boiling points can be separated by simple distillation.
- This statement is also true based on the principles of distillation.

4. **Conclusion**:
- Both the assertion and the reason are true.
- The reason correctly explains why the assertion is true, as the difference in boiling points is indeed more than 20°C.

5. **Final Answer**:
- Therefore, the correct choice is: Both assertion and reason are true, and reason is the correct explanation for the assertion.
