1. Contrast the reaction to form biodiesel with the reaction to form soap. Why do they form dif- ferent products given that both reactions start out with a base and a fat or oil? 2. Draw the structure of a fat or oil molecule that contains 1/3 lauric acid, 1/3 palmitic acid, and 1/3 oleic acid in its composition. Is the structure you drew the only unique answer pos- sible? Explain. 3. Do a specific calculation of the amount of NaOH required to make a soap that is made by saponifying a mixture containing 20% avocado oil, 30% lard, and 50% canola oil. Assume that the total weight of the three fats/oils is 100 g and a superfat of 5%. 4. Give possible structures of the main components in a soap where the fat or oil was saponi- fied with only two-thirds of the correct amount of sodium hydroxide. Use a generic fat or oil where the alkyl portions are represented by an R group. 5. Detergents are often used rather than soaps. Using an Internet search, find the structures for several detergents. What advantages do detergents have over soaps?
