Dehydration of alcohols follows E1 or E2 mechanism. The primary alcohols, elimination reactions follow the E2 mechanism whereas the secondary and tertiary alcohols elimination reaction follows the E1 mechanism. Basically, it follows a 3 step mechanism. The steps that are involved are explained below:
Dehydration reaction is a type of chemical reaction wherein water is formed from the extraction of the components of water from a single reactant. An alkene is produced when dehydration of an alcohol is performed.
The mechanism of dehydration may vary from alcohol to alcohol even when the same catalyst is being used.
