Question

why is factional distillation is better than that of simple distillation​

Answer 1

Answer:

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.

Answer 2

Answer:

factional distillation is better than simple distillation because we get so many products after factional distillation
