How will you collect data for this experiment? (39pts) Report Sheet From the procedure Choose four of the esters listed in Table E.1 in the lab mnaual that have a fragrance and determine the appropriate acid or acid anhydride and alcohol to prepare the ester. Use the relevant procedure based on whether starting with an acid or an acid anhydride. Refer to the lab manual for the synthetic procedures for the synthesis of esters from acetic anhydrides and the synthesis of esters from acids. In the table below, choose the four unique esters you want to synthesize. For each ester, select the method of preparation (synthesis from an acid anhydride and synthesis from an acid). Based on the method used, select the necessary reactants that will produce your chosen ester.

(5pts) Describe the procedure for the preparation you chose for each ester. Make sure the procedure matches the method you selected above and that you include all reagents, Normal : BIUX, X === fx Ester 2 Same as above but the acid and alcohol are different Ester 3 Same as above but thed acid and alcohol are different 8 Ester 1 Formic acid and butylalchohol and catalytic H2504 are heated which creates the butyformate The reaction is neutralized by using aqueous NaOH. The diethyl ether rids of the reaction mass. The ether is then distilled to get rid of the crude butyl formate, the crude is purified by distillation Ester 4 Same as above but the4 acid and alcohol are different C 0₂ EBT & IT Saved
