Question

write the three steps involved in the mechanism of acid catalysed dehydration of ethanol to ethene?​

Answer 1

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

1.Protonation of ethanol to form ethyl oxonium ion:

2.Formation of carbocation (rate determining step):

3.Elimination of a proton to form ethene: The acid consumed in step 1 is released in Step 3.
