During this experiment the starting materials, cyclohexanol and 85% phosphoric acid were reacted to produce a cyclohexene product. The product was obtained at a 42.63% yield. The product was then identified using chemical tests and GC and IR tests. The first chemical test performed was adding bromine in dichloromethane to a sample of cyclohexane. The color of the sample changed from a red-brown to a clear color indicating that the sample was cyclohexene. The second chemical test performed was adding potassium permanganate to a sample of cyclohexene. Again, the color changed from purple to clear with a brown precipitate on the bottom once more indicating that the sample was in fact cyclohexene. Examining the IR test, it is evident that cyclohexene is present due to the peaks at the frequency range of 2900-3022. The typical range of an alkene is between 3000-3100. The GC test showed that the final product was not 100% pure. There were two peaks on the GC test one of which had an are percentage of 99.25%. This means that there may have been a small amount of impurities in the sample such as water.
