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.

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.

Mixtures that can be separated by simple distillation are-

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : A simple distillation can be used to separate a mixture of propanol and propanone. Reason (R) : Two liquids with a difference of more than 20^(@) C in their boiling points can be separated by simple distillations. In the light of the above statements, choose the most appropriate answer from the options given below :
