Question

33. Which distillation method is used for
the separation of high boiling substances
from non-volatile impurities?
O A) Rectification distillation
O B) Steam distillation
O C) Simple distillation
OD) Vacuum distillation​

Answer 1

Explanation:

Vacuum distillation is used to distill compounds that have a high boiling point or any compound which might undergo decomposition on heating at atmospheric pressure. The vacuum is provided either by a water aspirator or by a mechanical pump.

Answer 2

Answer:

Fractional distillation

Fractional distillation leads to a better separation than simple distillation because the glass beads in the fractionating column provide "theoretical plates" on which the vapors can condense and then re-evaporate, and re-condense, essentially distilling the compound many times over.
