If the boiling point difference between that two liquids is not much, the…..method is used to separate them

Options

A. simple distillatin
B. distillation under reduced pressure
C. steam distillation
D. fractional distillation

Answer

D

Explanation

When difference in boiling points between the two liquids is-not much, differential extraction is the most suitable method to separate them. The liquid with lower density floats over the liquid having higher density, thus can be easily separated.
