bromination reaction by addition of concentrated HBr and a 30% H2O2 solution‚ followed by an extraction of the aqueous phase. This produced trans-1‚2-dibromocyclohexane (product: 12.8886g‚ 67.34% recovery). The trans-1‚2-dibromocyclohexane was reduced by zinc metal to cyclohexene. The reaction was conducted in water‚ first allowing the reaction to reflux and then isolating the cyclohexene by distillation (product: 4.2144g‚ 95.89%). Introduction This experiment carries out a series of steps to carry out
