QuestionAnswer
Early fractions are more or less cyclohexane-rich More
Late fractions are more or less toluene-rich More
Fractional distillation gives ____ Purer fractions than simple distillation
What does the x-axis of GC chromatogram show Retention time (Rt)
What does the y-axis of GC chromatogram show Detector response (signal intensity)
Each compound produces ____ peak(s) One
Area under the peak is proportional to ____ Number of moles of that compound
What is used to determine the response factor Equimolar mixture
Which compound is always the first peak Cyclohexane
What is used to match each compound's retention time Pure cyclohexane and toluene chromatograms
What determines composition Peak area -> not height
What does the equimolar sample do Establishes calibration and confirms which peak is which
Why does fractional distillation achieve higher purity It has repeated vaporization-condensation cycles instead of just one
