E1 dehydration of alcohols
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 WebDehydration of alcohols can often synthesize alkenes (and water), and this process is often performed by heating the alcohol in the process of a …
