Question

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

Answer 1

Answer

The mechanism of acid dehydration of ethanol to yield ethene involves the following three steps:

Step 1:

Protonation of ethanol to form ethyl oxonium ion:

Step 2:

Formation of carbocation (rate determining step):

Step 3:

Elimination of a proton to form ethene:

Answer 2

The system of corrosive parchedness of ethanol to yield ethene includes the accompanying three stages:

Protonation of ethanol to frame ethyl oxonium particle.

Development of carbocation (rate deciding advance). Disposal of a proton to frame ethane.

The corrosive expended in stage 1 is discharged in Step 3.

After the arrangement of ethene, it is evacuated to move the balance a forward way.
