How will you collect data for this experiment? (39pts) Report Sheet From the procedure Choose four of the esters listed
Synthesis of Esters 1 W N 3 4 Ester Chosen Choose ethyl butyrate Choose amyl acetate Choose 1-octyl acetate ▸ C Choose isobutyl formate- Preparation Used Choose... From acid Choose From acid Choose From acid Choose From acid Reactant 1 (acid or anhydride) Choose butyric acid Choose acetic acid Choose acetic acid Choose formic acid Y Choose Choose... Reactant 2 (alcohol) Choose amyl alcohol Choose 1-octyl alcohol Choone isobutyl alcohol (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.
(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
