Write the mechanism of acid catalysed dehydration of ethanol to ethene.

Text Solution

Verified by Experts

a) Mechanism involves the following steps.
Step - 1 : `ul("Protonation of alcohol")`: Alcohol combines with a proton to form a protonated alcohol.

Step - 2: `ul("Formation of carbocation")`: The protonated alcohol loses a water molecule to form a carbocation.

Step - 3 : `ul("Elimination of a proton")`: The carboncation then eliminates a proton and undergoes rearrangement of electrons to form the alkene.
