By using phosphoric acid, dehydration of cyclohexanol was possible. Also, to determine if it was whether alkene or alkane, bromine was used to yield a trans- 1,2-dibrominated product. Oxidizing cyclic alkene to a dicarboxylic acid. Having used all the procedures done before this experiment such as finding melting points, densities, molecular weights, and more combination of extraction, distillation, recrystallization, chromatography was done. Chromatography displays how polluted it is with different liquids. It was about 85% cyclohexanol and 15% something else. In its cyclohexene at about 2900 and 1440, there was a scan done. Higher the temperature of the liquid was, the longer the compounds need which results in better separation. Exactly 2.02 grams of cyclohexanol was used and having to find % yield, different combinations of methods were used to recover. Boiling points were at 63 to 69 degrees as first drop occurred at 66 degrees. At the end, 0.313 grams were recovered which is about 15.5% recovered from the total 2.02 grams used. The second part of the experiment was with cyclohexene and cyclohexane. Depending on which liquid was used, the colors were changed. Bromine in dichloromethane and 1% potassium permanganate and 10% sulfuric acid were used. The only unaffected color was cyclohexene with bromine in dichloromethane. All the other three tested were affected. Using cyclohexene with potassium permanganate with sulfuric acid turned it dark purple. Cyclohexane made the two given liquids either reddish-orange (with bromine in dichloromethane) and dark purple (with 1% potassium permanganate and 10% sulfuric acid).
