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?

  • Chemistry -

    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.
