The starting materials were reacted using conditions specific to the reaction being performed and the target product was obtained in 35.7% yield. This number is low, so it is not likely that pure cyclohexene was obtained through this experiment. The experimental boiling point was determined to be 70°, which is not what it should be, as the actual boiling point if Cyclohexene was 83°. The GC run showed a reaction time of .207 which is too low to be Cyclohexene.Also, based on the IR abortion, there was a peak for an aromatic ring and for a C-H bond. Based on the bromide test and the potassium permanganate alkanes should be present. The color from the bromide test was brown and there was precipitate on the bottom. The potassium permanganate test showed up purple. So both of the tests ran by the TA expressed that pure cyclohexane was not formed, but the test that were done chemically showed that it was formed.
