Question

A) If your distillation provided complete and perfect separation of the two substances, what would the GC results look like for the 2^nd mL sample vial and the 6^th mL sample vial?

B) Your two liquids differed by 24°C in boiling point. How would your GC results for the 2^nd mL sample vial have been different if the liquids differed by 100°C?

Answer 1

A) Your question is imperfect. Either mentioned 2 mL and 6 mL sample vial or 2nd and 6th sample vial. I am providing solution for both the cases.

For 2 mL and 6 mL sample vial:

GC result does not differ for volume of sample. It differs only based on concentration or purity.

So if your distillation cuts are 100% pure you will get same peak at same RT (retaintion time) nfor both 2 mL and 6 mL sample vial.

For 2nd and 6th sample vial:

Let's take two compounds are A and B having RT (retaintion time) x and y respectively. And the boiling point of B is greater than the boiling point of A.

Again take 2nd vial contains only Compound A and 6th vial contains only compound B (as bp of B is higher than that of A).

Then you will get peak at RT x for 2nd vial, and get peak at RT y for 6th vial.
