question_answer 1)

  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: (a) If both A and R are correct and R is the correct explanation of the A. (b) If both A and R are correct but R is not the correct explanation of the A. (c) If both A and R are not correct. (d) If A is incorrect but R is correct. (A) Simple distillation can help in separating a mixture of propan-1-ol (boiling point\[97{{\,}^{{}^\circ }}C\]) and propanone (boiling point\[56{}^\circ C\]). (R) Liquids with a difference of more than \[20{}^\circ C\]in their boiling points can be separated by simple distillation.

Answer:

  (a) Mixture of propan-1-ol and propanone have significantly different boiling point hence they can be separated by simple distillation.
