Verified step by step guidance1
Understand the concept of a dehydration reaction: A dehydration reaction involves the removal of a water molecule from a compound, typically resulting in the formation of a double bond or a new compound.
Identify the key components of the given options: Analyze each option to determine if it involves the removal of water.
Evaluate the first option: 'Addition of water to ethene' is a hydration reaction, not dehydration, as it involves adding water rather than removing it.
Evaluate the second option: 'Oxidation of ethanol to acetic acid' involves the addition of oxygen and removal of hydrogen, but not specifically the removal of water as a molecule.
Evaluate the third option: 'Conversion of ethanol to ethene' involves the removal of a water molecule (H2O) from ethanol (C2H5OH) to form ethene (C2H4), which is a classic example of a dehydration reaction.
