In gas chromatography, what would be the order of the retention times for your mixture (hexane and toluene)? What is the basis for your answer?
The retention times will depend on what you used as the stationary phase.
Hexane Bpt is about 70C and toluene is about 110C. So for a nonpolar column we would expect a boiling separation so the hexane retention time will be less than that for toluene.
