Some examples of small molecules that are byproducts of condensation reactions are acetic acid (CH 3 COOH) and methanol (CH 3 OH), but most often water (H 2 O) is formed from one molecule losing hydrogen (H) and another losing a hydroxyl group (-OH), especially in the biological reactions that take place in living things. One of the most common dehydration reactions involves the conversion of an alcohol to an alkene, as shown here, for the dehydration of ethanol to produce ethylene, also known as ethane.
