Questions & Step-by-Step Solutions

What is the main product of the dehydration of 2-butanol?
  • Step 1: Understand that dehydration means removing water (H2O) from a molecule.
  • Step 2: Identify the structure of 2-butanol, which has a hydroxyl (OH) group attached to the second carbon of a four-carbon chain.
  • Step 3: Recognize that during dehydration, the OH group and a hydrogen atom (H) from an adjacent carbon are removed.
  • Step 4: This removal creates a double bond between the two carbons, resulting in the formation of butene.
  • Step 5: Note that there are different types of butene (like 1-butene and 2-butene), but the main product is generally considered to be butene.
