Abstract. We present a laboratory experiment that covers the concepts of synthesis, NMR, and hydrogen bonding for a second-semester organic chemistry class for life-science majors. Two imines are synthesized from the addition of para-toluidine to either ortho- or para-vanillin through a solvent-less reaction. Students use their acquired 1H NMR spectra of each imine to determine which imine possesses an intramolecular hydrogen bond. This experiment helps provide a clear connection between organic chemistry and biological sciences.

Key Words: Laboratories and Demonstrations; organic chemistry; carbon nanotubes dispersion; polymer (poly-3-hexylthiophene); environment; sensor development and electrochemistry (square wave anodic stripping voltammetry).
