Question

what is my limiting reagent, theoretical yield calculated from moles , and % yield for the synthesis of banana oil?

Isoamyl acetate (banana oil) is made by the acid catalyzed reaction (fischer esterification) between isoamyl alcohol and acetic acid. sulfuric acid was used as the catalyst for the fast conversion of product from starting alcohol and acid. the catalyst only affects the rate of the reaction not the extent of the reaction.

here is the data from lab:

Mass (9) of 1s.58) Serew viel +ISoany altoho Cap mass ( of screw car vial (emptu It.981 Volume (m) of acetic acid 7 ML Mass ) of final diy praduet Scvew Cap via 13,310 Reflux Stort:9:40 PAM eND:10:0 AM 1.3346 Le fractive (udex at 27, 8°C ISoamy alcohol sed: I5.S81 -11.98/ 3.6 acetic acid= 7mL X

here is the table that I need help with. I need the limiting reagent, experimental yield, and %yield.
