Discuss qualitatively the effectiveness of the separation identifying peaks (if any) in the IR that appear to result from the lower boiling solvent.
Hi there! Unfortunately, we don't have support for laboratory lessons :( . You can submit the details of the IR details of the molecules and I think we can help you with that.
Fractional Distillation is a more accurate way of finding differences in boiling points because of the increase of surface area because of the copper placed in the head. It will also give you a sharper more precise peak on the graph between the boiling points.
