Suha Kadura 10/28/08 Organic Chemistry Lab Tuesday 1pm - 4:30pm (AWeek) Synthesis of Isopentyl Acetate Results In this experiment the isopentyl acetate was synthesized from acetic acid and isopentyl alcohol. Isopentyl Acetate is an ester. After synthesizing the isopentyl acetate and calculating the percentage yield (shown on attached page), the results were then analyzed on an IR spectrum. According to my IR spectrum (also shown on attached page), there was a peak at 1738.76 (representing the C=O group), which reveals the presence of an ester. This proves that the synthesis of the reaction was correctly carried out. At about 2959.44 there was a peak indicating the presence of a C-H aliphatic group. Finally, in the fingerprint region at about 1229.18 (stronger peak) and 1054.16, there were peaks representing C-O groups, which is present in an alcohol. Discussion When comparing my IR spectrum to the starting material spectrum (isopentyl alcohol), one can see that the peak at about 3000-2850cm
