Questions & Step-by-Step Solutions

What is the product of the dehydration of ethanol?
Correct Answer: Ethylene (Ethene)
  • Step 1: Understand that dehydration means removing water (H2O) from a substance.
  • Step 2: Identify the substance we are working with, which is ethanol (C2H5OH).
  • Step 3: Recognize that during dehydration, ethanol loses a water molecule.
  • Step 4: Write the chemical equation for the dehydration of ethanol: C2H5OH → C2H4 + H2O.
  • Step 5: Notice that after removing water, we are left with ethylene (C2H4), also known as ethene.
