What method should you use to separate this sample of mixture?

a mixture of several liquids with boiling points that are different but close together.

a. column chromatography
b. fractional crystallization
c. simple distillation
d. fractional distillation
e. paper chromatography

The answer to your question is: D. Fractional distillation

Explanation:

A. Column chromatography  this method is use to separate mixtures base in its capacity to be absorbed.

B. Fractional crystallization  this method use the solubility of solutes in a solvent.

C. Simple distillation  is a method to separate 2 liquids based on the difference in their boiling points.

D. Fractional distillation  is a method used to separate a mixture of liquids which have their boiling points very close.

E. Paper chromatography is a method to separate a mixture based on their different rate of migration on a paper.
