This research aims to assess how students approach conjugated molecules and draw conclusions regarding acidity, H chemical shift, and geometry. Chemical shift and geometry 85 concepts have been explored much less than acid-base chemistry. With chemical shift, research studies have focused on relationships with the inductive effect and pKa but to a lesser extent than resonance. Lecture discussions emphasize the relationship between hybridization, resonance, and geometry with molecules such as amides. The text used for our organic chemistry course specifically notes the correlations with these factors. Three different 90 contexts were identified -all of which can be solved using resonance as the basis for the study.
