In Organic Chemistry II for the 'Preparation and Properties of Soap' lab, please help answer the following questions; 1. Write out a step-by-step mechanism for saponification. You may begin with a simple ester such as ethyl acetate. 2. The experimental procedure directs you to generously lubricate (grease) the ground glass connection between the 10 ml r.b flask in which saponification is being carried out and the reflux condenser. Why is this generous lubrication needed?
