Given below are two statements : one is labelled as Assertion (A) and the other is labelled as
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 :
  1. Both (A) and (R) are correct but (R) is not the correct explanation of (A).
  2. Both (A) and (R) are correct and (R) is the correct explanation of (A).
  3. (A) is true but (R) is false.
  4. (A) is false but (R) is true.

Solution

 Simple distilation is the method of separating mixtures based on differences in their volatilities in a boiling liquid mixture. The components in a sample mixture are vaporised by the application of heat and then immediately cooled by the action of cold water in a condenser. Two liquids with a difference of more than 20°C in their boiling points can be separated by simple distillations.
