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.

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

Text Solution

Verified by Experts

The correct Answer is:
A
Both A and R are correct and R is the correct explanation A.
Simple distillation can be used to separate a mixture of two liquid which do not react and have boiling point difference of more than `20^(@)C`. Hence, a mixture of propan-1-ol and propanone can be separated.
