Question 9

Jack and Jill performed experiment 4.4, the separation of cyclohexane and toluene by fractional distillation. During the course of the experiment, both students measured their reflux ratios several times. Jack's reflux ratio averaged about 10:1 while Jill's averaged about 5:1. Who probably obtained the best separation of the two liquids?
Answer
A. Jack
B. Jill
C. Not enough information to decide, i.e. need to know the size of the 3 fractions they collected
D. Reflux ratio really has nothing to do with how well the two liquids are separated
