Why Are 1H NMR Integrations Not Perfect? An Inquiry-Based Exercise for Exploring the Relationship Between Spin Dynamics and NMR Integration in the Organic Lab  Haim Weizman
When FT-NMR is used to collect data without a sufficient delay time between subsequent pulses, the integrated area under certain peaks may result in a lower value than should be observed under appropriate conditions. This exercise is designed to raise awareness of this issue in students and to serve as an inquiry-based stepping-stone into basic FT-NMR.

Using Building-Block Puzzles To Practice Drawing Organic Mechanisms  Ender Erdik
This pencil-and-paper activity is designed to test the ability of students in writing intermediates and products in the reactions of ketones. An undergraduate student who is successful in organic chemistry at the sophomore level is expected to fill in empty boxes with the appropriate "building blocks", which are atoms and atom groups (neutral or ionic). Solving the puzzle will give the formulas of reactants, reactive intermediates, and products. Students test their understanding of reaction mechanisms while having fun.
