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? KOH он + excess CH3OHHO OCH3 Figure 1: Synthesis of biodiesel from vegetable oil. Alkyl groups (R) vary depending on which vegetable oil is used.
RCOR’ + R’’OH → RCOR”
