Document Summary
Preparation of alkenes by e1 and e2 elimination reactions, The objective of this lab is to prepare distribution of alkenes by e1 and e2 reactions. To isolate the products fractional distillation will be used. Further on, to confirm the functional groups in the products, baeyer and bromine classification tests will be done. Finally, gc analysis of the products would help to calculate the mole percent and percent yield of the final products. There are two types of elimination reactions which produces alkenes as the products. In dehydrohalogenation reaction (e2), the carbon-halogen bond and adjacent carbon-hydrogen bonds are converted into carbon-carbon double bonds whereas in dehydration reaction (e1), the carbon-hydroxyl bond of a tertiary alcohol is converted into a carbon-carbon double bond. Figure 2: e2 reaction performed in this lab. Figure 1 shows the dehydrohalogenation reactions which is also known as e2 reaction where e refers to elimination and 2 refers to the molecularity of the rate determining step.
