Question

any two differences between fractional distillation and simple distillation

Answer 1

Fractional distillation is essentially the same as simple distillation except that a fractionating column is placed between the boiling flask and the condenser. The fractionating column is usually filled with glass or plastic beads. These beads improve the separation between the liquids being distilled.

Answer 2

fractional distillation uses fractions for distillation whereas simple distillation does not have fractions.

Fractional distillation is used to separate liquids with close evaporation points whereas simple distillation is used to separate liquids with far evaporation points.
