Assertion : Glycerol is purified by distillation under reduced pressure. Reason : Organic compounds in liquid state are purified by distillation.

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion.
  • Correct answer
    B
    If both assertion and reason are true but reason is not the correct explanation of assertion.
  • C
    If assertion is true but reason is false.
  • D
    If both assertion and reason are false.

Solution

Glycerol (b.pt. $292^{\circ} \mathrm{C}$ ) decomposes on heating below its boiling point and therefore it is distilled under reduced pressure.

Hence, the correct answer is option: 'B'.
