Problem: 1. Draw a detailed, stepwise mechanism for the transesterification reaction that forms the biodiesel product in this reaction. You may use a generic representation of the triglyceride as shown in Figure 1. 2. What is the generic structure of a soap? Explain how soap forms in this reaction. If anhydrous methanol is used, how is water getting into the system? Figure 1: Synthesis of biodiesel from vegetable oil. Alkyl groups (R) vary depending on which vegetable oil is used.
