The Aldol condensation questions were part of an extended survey that compared E1, E2, and E1cB mechanisms. As shown in Figure , a detailed mechanism was provided for the Aldol condensation as a reference. This report will focus on two specific questions from the survey: Which 105 step of this reaction is the least thermodynamically favorable? Why is the step you selected the least thermodynamically favorable? The validity of the question was assessed by organic chemistry II instructors. Additionally, Chang and Perrin provided detailed energetic information for the specific reaction analyzed.
