GC Trace 3 GC Trace 4 during GC because it has a (lower, higher) boiling point. ii. (1 point) Isobutyl isobutryate elutes (first, second) and has a (smaller, larger) retention time during GC because it has a (lower, higher) boiling point. iii. (4 points) Using the GC traces and listed areas above, calculate their % completion of the
