Question

What is acid catalysed dehydration means?

Answer 1

Acid-catalyzed dehydration is an important elimination reaction in organic chemistry, whereby water is removed from a compound. This chemical process is very important in converting alcohols into alkenes.So acid catalysed dehydration is the dehydration reaction of alcohols to generate alkene proceeds by heating the alcohols in the presence of a strong acid, such as sulfuric or phosphoric acid, at high temperatures.

During the process of acid-catalyzed dehydration, alcohols experience either E1 or E2 mechanisms that result in them losing water and thus forming a double molecular bond.Primary alcohols experience bimolecular elimination called E2 mechanism under this process, while secondary and tertiary alcohols experience unimolecular elimination or E1 mechanism.
The dehydration reaction of alcohols to create alkenes occurs through heating the alcohols at high temperatures in the presence of a strong acid, such as sulfuric or phosphoric acid. If the reaction isn't sufficiently heated, the alcohols don't dehydrate to form alkenes; instead, they react with each another to create ethers.
