In this experiment for an upper-division course in organic structure determination, each student prepares an unknown compound and characterizes the product using multiple spectroscopic techniques. The unknowns, 2-aryl-substituted 1,4-dihydro-3,1-benzoxazines and 1,2,3,4-tetrahydroquinazolines, are prepared in a single step by the condensation of…

An inquiry-based experiment for the organic chemistry laboratory was developed to provide students with a cognitively rich research experience. Student teams were charged with optimizing the reaction conditions for the Williamson ether synthesis of 2- fluorophenetole from 2-fluorophenol, ethyl bromide, and potassium carbonate in either absolute…

A hands-on educational module was created to illustrate the scope of chemical engineering. Students are taught fundamental concepts that they integrate in a laboratory experience designing and fabricating a 'plant-on-a-chip' microfluidic device capable of continuous processing of reactive flows. Students gain insight into chemical engineering…

The laboratory is a mainstay in STEM education, promoting the development of critical thinking skills, dexterity, and scientific curiosity. The goals in the laboratory for nonchemistry, prehealth majors, though, could be distinguished from those for chemistry majors. In service courses such as organic chemistry, much laboratory time is often spent…
