Harjit Kaur Chem 201 Lab 21 I A. Zaitsev’s rule: When HZ is removed from a species to form an alkene, hydrogen is lost preferentially from the carbon atom that has fewer hydrogen. In this experiment we were supposed to see the reaction of methylcyclohexanol and the dehydration of it, so we can see the formation of an alkene. Since the 4-methylcyclohexanol is a mixture of cis and trans isomers, we do not get a Zaitsev product. The tans reactant only gives product but the cis reactant gives 2 different compounds. The reaction goes through both E1 and E2 elimination. The major product of this reactant is not the most subsisted one. B. II A. 20.00 mmol of 4- methylcyclohexanol is put in the vial, and mix .70 mL of phosphoric acid. The apparatus for distillation is made. The reactants are then heated. The temperature is watched closely. Using a pipette the distillate is transferred to 2 vial 1 mL in to each vial. The temperature started to fall after the reaction was completed. The distillate is then washed with sodium bicarbonate and the aqueous layer is removed and
