Explain the mechanism of acid catalysed dehydration of butanol

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:



The acid CONSUMED in step 1 is released in Step 3. After the formation of ethene, it is removed to SHIFT the equilibrium in a forward direction.
