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 give
Options
- ABoth (A) and (R) are correct but (R) is not the correct explanation of (A).
- BBoth (A) and (R) are correct and (R) is the correct explanation of (A).
- C(A) is true but (R) is false.
- D(A) is false but (R) is true.
Correct answer
B. Both (A) and (R) are correct and (R) is the correct explanation of (A).
Step-by-step 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.
