WebDehydration Objective To perform a unimolecular elimination (E1) reaction and use gas chromatography to determine the product distribution. Background Alcohols are not good leaving groups. However, the addition of acid to an alcohol converts the bad hydroxyl leaving group to a good leaving group, water. OH + H+ – H+ H2 eq 1 WebSee Page 1. E1 mechanism for 2- propanol Step 1: An acid/base reaction. Protonation of the alcoholic oxygen to make a better leaving group. This step is very fast and reversible. The lone pairs on the oxygen make it a Lewis base. Step 2:Cleavage ofthe C-Obond allows the loss of thegood leaving group, a neutral watermolecule, to give a ...
