Which functional group is formed when an alcohol undergoes dehydration?

Which functional group is formed when an alcohol undergoes dehydration?

Step 1: Understand what an alcohol is. An alcohol is a compound that contains a hydroxyl group (-OH).
Step 2: Know what dehydration means. Dehydration is the process of removing water (H2O) from a substance.
Step 3: Recognize that when an alcohol undergoes dehydration, it loses a water molecule.
Step 4: Identify the result of this process. The removal of water from the alcohol leads to the formation of a double bond between carbon atoms.
Step 5: Conclude that the product formed is an alkene, which is a type of hydrocarbon with at least one double bond.
