Question
if you were to return your 97-106 C fraction to the empty boiling flask and redistill it, you might expect it all to distill between 97-106C as it did the first time. It actually yields some distillate in all four boiling ranges. EXPLAIN WHY? if you were to return your 97-106 C fraction to the empty boiling flask and redistill it, you might expect it all to distill between 97-106C as it did the first time. It actually yields some distillate in all four boiling ranges.

This is due to the reflux. In theory, the reflux will allow you to do a "perfect" ranged distillation. In reality, we use reflux according to efficiency and cost of operation. Many times we require high refluxes in order to achieve 100% of separation.
In real life, this is not possible, we set a convinient relux ration and operate it. Therefore, if you re-distill the range product, you will not expect 100% to be distilled in this set of ranges.
NOTE that when we design this, we "assume" a perfect set of disitillation. Now a dyas we use software program to mdel such distiallations instead of ideal or "perfect" separations
