Question

Which one would elute first from the column chromatography that has a stationary phase and a weak polar solvent?Explain your answer.

 

A)Hexane

B)Hexan-1-ol

C)Hexene

D)Hexan-1-one

Answer 1

A weak polar solvent would tend to elute the less polar molecules first.  Thus, hexane would probably be the first to be eluted, since alkanes are SLIGHTLY less polar than alkenes.
