Answer:
Water (H₂O) Molecule
Step-by-step explanation:
This is why this process is usually called a dehydration/condensation process. The reason a water molecule is produced as a by-product is that one end of the one monomer involved in the bonding releases an –OH while the other monomer releases an – H before a bond joining the two monomers is formed. These two radicals combine to form a water molecule (OH⁻ + H⁺ → H₂0).
