Q. 55

In the following questions a statement of Assertion (A) followed by a statement of

Reason (R) is given. Choose the correct option out of the choices given below each question.

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.

(i) Both A and R are correct and R is the correct explanation of A.

(ii) Both A and R are correct but R is not the correct explanation of A.

(iii) Both A and R are not correct.

(iv) A is not correct but R is correct.

Answer :

Mixture of propan-1-ol and propanone can be separated by steam distillation,as Simple distillation can be used to separate a mixture of two liquid which do not react and have boiling point difference of more than 20oC.

Hence, both assertion and reason are correct and also reason is the correct explanation
Hence, option (i) is correct.
