Level 3 – Chromatography – Columns vs TLC TLC plates are essentially miniature column chromatography experiments. The order in which the analytes travel is proportional to the order in which the analytes would elute off of a column. Four compounds consisting of propanol, cyclohexene, 3-amino-hexanoic acid, and acetic acid, were combined and added onto a silica gel column with a mobile phase of hexane:ethyl acetate (10:1 v/v). Predict the compounds elution order from first to elute (1) to last to elute (4) based on IMFs.

Level 1 – Melting Point – Relative Comparisons The following statements are comparative to one another. Fill in the blank to create two true statements. Melting point ranges for pure substances are ____________; in contrast, melting point range for impure substances are ____________ .

In this course, we will have a report project. This project includes several assignments, such as an annotated bibliography. How will we complete the bibliography?

Changes to the course schedule, assginments, and syllabus are subject to revisions. Changes will be posted and announced in Blackboard.
