Dehydration of Alkanols (dehydration of alcohols) Chemistry Tutorial
Alkanols belong to a class of organic compounds known as alcohols . Alcohols, and therefore alkanols, contain the OH (hydroxyl) functional group which is the active site on the molecule. Dehydration of alkanols (alcohols) is an elimination reaction . Water is eliminated from the alkanol resulting in an alkene . alkanol → alkene + water.
