Level 1 – C-NMR Signal Prediction How many signals would Acetone show on a decoupled 13C-NMR spectrum?

Level 3 – IR Spectrum Reading (1 of 2) A: B: C:D:  Which of the spectra above would would least likely correspond to carbonyl containing compound? 

Level 2 – Recrystallization – Solute Properties Based on Solubility Given the following information concerning Compound Y: Compound Y did not dissolve at all in benzene at any temperatures. Compound Y dissolved completely in hot, but not cold propanol. Compound Y dissolved completely in an water at all temperatures. What can be inferred about the compound Y’s polarity?

Level 2 – TLC – Standard Phase Conditions When examining cyclohexanone, which of the following IMFs described below would be likely responsible for keeping the Rf low during a standard-phase TLC experiment?

Level 1 – UV Characterization Which of the following functional groups is the least UV active?Note: This is not asking about fluorescence.

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. 

Unless given permission to use AI tools, each student is expected to complete each assignment without substantive assistance from others, including AI.
