For the reaction between bromine in chloroform (CHCL3) and cyclohexene, the observation was a depolarization of bromine, from the reddish bromine to colorize. Mass the product and find the % yield This is % yield 58% % purity 100%. 5. Cyclohexene. 0000071116 00000 n The mixture was distilled and distillate was collected into the receiver flask. a. Why is saturated sodium chloride, rather than pure water, used Boiling points were at 63 to 69 degrees as first drop occurred at 66 degrees. Hydroxyl group is poor leaving group, sulfuric acid is used , in this way the hydroxyl group pulls off proton from sulfuric acid and a protonated cyclohexanol is obtained. Discard the lower aqueous layer in a separating funnel. x\[o8~Gy6VDR`im }h';u_?qDRvd)2EsH_l>if}9U7M}fya]z}iwuz$%(gOh}z-Fd1)2tynSVl@R^vz%B??NO>+n 1E4F&G[Bo.vL!J#Go_ t/?^EN[|OFu3fn4?LFdFvL0n'"Li.&wi7r,UEX RL"cx#y. The diol synthesized can then be transformed to carboxylic acid, ketone or aldehyde according to the applied conditions. Instructor Test Bank. 0000000893 00000 n 321 0 obj <> endobj The only unaffected color was cyclohexene with bromine in dichloromethane. On the other hand, during the transfer of cyclohexanol to the pot, a significant amount could have been lost. hbbd```b``3@$?XLE"Y]`:0 I 0V sals have a stronger attraction to water than to organic solvents. The cyclohexene can prepared from cyclohexanol by an elimination method and tested that it was unsaturated. Since the anhydrous sodium sulphate is a very good dehydrating agent, it is used to remove the water in the mixture with cyclohexene. We will use the cyclohexanol that we purified in our previous experiment . The phosphoric acid is a catalyst and as such increases In this experiment, 1 of saturated sodium chloride is used to rinse the Hickman head It formed a double bond on cyclohexene, this also has a lower boiling point than % purity 100%. surround the receiving flask, set up condenser hoses properly and check The second step is the loss of water to form the carbocation. to the sp 3 carbon is responsible for the out-of-plane bending.
