Questions: 1. Give the step-to-step mechanism for the condensation of vanillin and creatinine. (based on what you did for this experiment, decide if you have an acid or base catalyzed reaction) 2. This aldol condensation does not require a base. Why? 3. What is the major difference between the IR spectra of vanillin and the condensation product?
