Question

18. Each purification technique relies on differences between physical properties to allow se the components of a mixture. For the techniques listed, ill in that particular specific physical propertion of other words, how does each technique accomplish the separation of different compound s? (3 pt) Purification Technique Physical property which differs between compounds to allow separation Chromatography Extraction Distillation 19. Typically, what type of compound elutes from a flash column first? How does this compare with its Rf ompound as seen on TLC? (3 pt)

Explanation / Answer

Chromatography: This techniques seperates different components based on their interaction with a material (on their way of travel through the phase)

Extraction: Solute is seperated based on its solubility in different phases.

Distillation: Boiling points of the components in the liquid mixture is the physical property based on which seperation takes place.

answering the first question as per the policy guidelines.
